So I can't get my desktop OR laptop running XP Pro 32 to even recognize the phone. As in no audio plays and nothing appears in the system tray. Tried with/without debugging mode, installed the samsung drivers etc. The phone doesn't even show up in device manager at all- not even as something unrecognizable. Its as if the port is dead. The phone does 'ding' though and charge ok so it is receiving power... though nothing at all appears in the android notification tab when connected. Any ideas or anyone know of any apps on the pc or android side to take a closer look at whats happening on the bus?
The only way that I can get it to work is to put it in media mode. It shows up as a media device in Win7. If I put it on, "ask every time" or whatever it doesn't work and in mass storage mode it shows up as two unreadable drives, they are grayed out in Explorer... Basically...don't use the "ask every time" for USB function.
This function seems like such a simple thing, not sure why Samsung has so many issues with it considering they have been making media devices for a long time.
Anyway... do you have access to a newer OS to at least rule that out as a cause. Not saying it shouldn't work with XP 32 but just something to check out.
I was having similar issues at first. I take it adb doesn't work either? Well my fix was to delete my whole Android SDK folder, then I redownloaded it (though I just kept the "tools" folder this time). Then I downloaded "USBDeview" (google it) to delete every USB driver that had to do with android (basically just left the printers, HID, and my Sansa drivers), restarted, then I downloaded the samsung drivers from the thread on here, plugged my phone in and manually pointed the driver search to the drivers.
ADB and Mass Storage has been working fine since. All I can tell you is to keep checking cause there's something you're missing, I also thought to myself "what the heck else can I do?" since I had done each one of those steps previously, but maybe I just had to do them all together. Good luck.
another possible solution is to change cables if you're not using the samsung provided cable - some cables are charger only (no data) - some of the motorola cables are charger only and we've already had one poster that had that issue
I couldn't get it to work at first either. I more or less did this.
I plugged in my phone. I did not enable mass storage mode on my phone. Walked away and let my PC think for a while. I came back and I noticed I had two new drives. I then enabled mass storage mode and could connect.
Two of my machines I had to do this. I'm not sure why it wasn't instant, but it just took a bit of patience and walking away from the machine to let it think for a while before I guess it installed the drivers and made its peace with the fact it wasn't the G1 any more.
Say into voice dialer "Open SD card" -> check "Enable USB mass storage". That works if port on PC is OK.
If it's a driver issue, open device manager and uninstall the usb ports. Unplug everything from usb and when you reboot the computer it will automatically reinstall the usb ports.

I ran into the same issue. It was a problem with the USB cable I was using. As soon as I tried a different cable it worked fine.

I second this, I forgot my sammy cable at work on Friday and on way home stopped at T-Mo and picked up a charger w/cable and realized right away this was just a charging cable as soon as I connected it to my PC. I'm returning the cable back to T-Mo tonight. At least I was able to charge my phone over the weekend.
UPDATE: You guys are right, it is the goddamn cables! I bought an extra wall charger + cable at the t-mobile store and was using that at home. I had left the original in-box cable at work. Tried the cable at work today and now the drives pop up. Still don't appear writeable but I can look into that when I have time, probably the typical driver issue. As far as I can tell those separate cables are power only! $15 for a two wires + dc adapter. Thanks Samsung. Grr.
i suspect the mfgrs have gone to charge only cables to help keep folks from tethering - just a suspicion
if the "drives" are popping up, have you "mounted" the phone (pull down notification bar, clik on USB connected and it should give you a window asking to mount the cards or drive)
FYI....The Rocketfish cables you get from Best Buy do not work. They are only capable of charging.
@larryccf...I don't think certain manufacturers are implementing this on purpose so we can't tether. I think their just being cheap.
Where I got my cables on the cheap! and my problem.
I got my cable at monoprice.com. Check it out that is a 10 foot usb cable for $1.69 and it works for me. They have different lengths and even some colors. Now my Mass Storage issue . . .
My Mass Storage via USB works fine unless I enable "USB Debugging" which one of my apps needs to work. Once debugging is enabled I loss the ability to see my sd card and internal storage on my XP netbook. any ideas????
Same Problem
I have the exact issue, tried many things have'nt found a fix yet. Any help would be greatly appreciated!!!
Thanks,

Yes phone is mounted, and can be seen w/o usb debugging enabled. However with usb/debugging on it does not read the phone being connected. Meaning that I cannot connect to ADB which is my main concern.

This is my issue exactly, and I haven't found a fix either. Called T-Mobile and they thought turning off debugging was the only fix I needed.
Most of them, sorry to say are half retarded. They think a data reset is the cure-all

Ain't that the truth!
If you are running windows (x86 or x64), it would be wise to install the samsung drivers. I was having this exact problem, but as soon as I installed the drivers from samsung, viola!
I had the latest drivers from google, and they did not work for me.
Here is a link to the thread containing the links to the drivers, thanks to TGA_Gunnman:

Hi all.
Is there a way to access the FAT32 partition on the SD through the USB cable (the same way I used to do with the Magic)?
Disabling the USB debug mode won't help!
Thanks.
Yes, just plug it in and there should be a notification asking if you want to 'mount' the storage. When you mount the storage it will become visible to your PC just as if it was a usb memory stick.
so for the idiot's guide (not calling you and idiot, but you clearly have not read the manual).
When you plug the usb cable in, at the top of the phone screen there should be a usb sign.
drag the notification bar down.
there should be a line for usb stating click to mount.
Click.
A popup will ask you do you want to mount, click 'mount'
DONE!
Please remember to unmount when disconnecting. do this either by ejecting the drive in windows OR the same method as mounting but the popup will ask you to unmount.
but again again again this is in the manual/.
And before I get any H8's saying you need to mount to access the manual, its also on the HTC site. so Raspberry to you.
It simply doesn't work. I did read TFR!
OK.
Are you trying this at work? It's possible through a windows reg change to disable the usb ports, my place does this but can be fixed with a simple reg script.
Have you another usb drive to try in the port you are using?
Just checking that your connecting it to the back of the computer as they are the main ports (ones directly connected to your mobo) as sometimes the front ones wont work if not connected/enabled.
If you do have another device/drive and this works in the port then bad times.

It would be more useful if you could tell us what it does do, rather than that it simply doesn't work.
1. When you plug the USB cable in, do you get "USB Connected" notification? If so, when you bring this up, do you get the option to mount the SD card?
2. Have you tried a different USB cable and/or connecting the phone to a different PC?
3. Have you tried with a different SD card in the phone?
4. Have you repartitioned your SD card in any way? (i.e. added swap, ext3 whatever?)
Regards,
Dave
1. No, I don't get any notification at all.
2. Different cables, same result. USB memory stick and USB hard drive work on the very same port.
3. Yes, same result.
4. Yes, I did the "usual" 3 partitions.
5. I'm running MoDaCo 2.1
FIXED while troubleshooting!
6. I switched to my Nokia DKE-2 cable and it magically worked.
7. The old cables used to work with ADB but not in storage mode.
8. All three cable can charge the phone.
9. I presume a problem with the cable, but have no idea about the nature.
Anyway, the thing was really not working at all. Please give first a look to my first post. I already tried a number of things before posting.

Just as a matter of interest, did you try with the cable that came with the phone? At the very least that should be working too.
Thus far, I've had no problems with 3 or 4 different USB cables, but I have seen issues like this in the past where cables didn't have all pins connected.
Regards,
Dave
I've lost my original cable some thousands kilometers away from home.
This is why I got using my digital camera and USB hard drive min-USB cables.
I got no problem so far apart of not being able to mount the phone's SD.
I presume a weird wiring problem. Maybe this thing can be put in a FAQ.
I am having a huge problem mounting my Epic 4G to my Mac. When I select Mount USB, nothing happens. I have read several posts about Galaxy S phones having the same problem, they all say to have USB Debugging turned on, but mine is on and still can't mount.
Also, another huge problem. I connect my phone, then I use adb to access the sd card, but I can only use adb for a short period of time, then it disconnects itself, then I try to run adb again but it does not recognize it. I have to unplug the phone, then plug it again.
Does anybody have any idea why this is happening or how to fix it?
Note: I can do everything perfectly fine with my Sprint Hero
Thanks

I've successfully mounted my SD card on OSX. I have debugging turned off. If it won't mount, try a different slot, if that doesn't work, try rebooting the phone. It will work.

Dude, welcome to the club. Since i got my phone i have not successfully been able to have it read on my Mac Mini. Tried different cables and different ports. Some say get a powered USB hub but i'm not in the mood to clutter my puny desk space.
For now i use an app called Websharing to transfer stuff via WiFi. It's a pain sometimes but that's how i get by for now.
I don't have any problem with 10.5 or .6
I can use either regular or debug. Sometimes rebooting the phone and/or the computer helps. It could be a crappy cable. I don't think the supplied one is very good. The one I use with no problems is the overpriced 3 footer that the corporate sprint stores have. I think the cables that came with the epic, moment, and evo were el cheapo. I had a problem that you are describing with a stock supplied cable. I figured out that the micro usb end wasn't making solid contact with the phone. If I would move the cable, it would disconnect. Changing to a real micro usb cable helped me. It could be the usb port is flaky or the usb plug is intermittent. If you are using vmware fusion or bootcamp or dual boot, see if it drops connection in a different os.
No luck under Windows7 (running with Parallels Desktop) either. I'll try buying a new USB cable and see if that works ... Will try Websharing too.
Thanks

Did you put your phone into debug mode?
I found that trying different USB slots on the PC, it will eventually work. When you plug it in the first time, it will install some needed drivers ABD etc, if you unplug the phone and plug it back into the same USB slot, it will install the last remaining drivers and you should now be able to see the phone.
Samsungs drivers are flaky at best. It took me a good hour to get it working for me so I could root my phone.

temporary fix
This topic has been discussed at another tread.... but anyway, The Macs (current generation only) do not give you enough energy at the USB to power the phone into connecting the memory card. Nor even enough to recognize the phone for more than a few seconds. You can get around it, temporarily, by connecting through a powered USB port. Tetheris still doen's work, but at least you can mount your sd card. It's a software issue... if you're running Windows on the mac machine, it'll connect and mount fine. So, ask Mac for a fix.

Yes..thanks. That did it for me. The only thing I hadn't tried was plugging it into my powered usb hub...boom it works.
Worked for me too... can't f'in believe it.
I cannot get my epic to mount for ANYTHING! I factory wiped the phone, nope, I used a palm pre usb cable nope, I downloaded the official samsung drivers nope, I plugged the cable into the motherboard on the computer nope, I tried a different computer running windows 7, nope tried a laptop using windows vista, nope. Does anyone know ANY WAY POSSIBLE to get this thing to mount? I selected mass storage and dissabled and enabled usb debugging. Im just not having any luck. It seems that the computer recognizes the phone is connected just cant get to the files on the SD card.
I also spent many hours trying to figure out what the hell was wrong with my Epic, that is, why it would come up as a "malfunction" in Windows when I plugged the USB cable in.
I tried drivers, different restore points, wiping, etc. etc. etc.
To the point... Try a new USB cable. The one packaged with the Epic is junk. As a matter of fact, it worked several times before it crapped out. I have no idea why, but I picked up a new micro USB cable, plugged it in, and the phone was then immediately recognized by my computer to allow mass storage mount.
People who tried the Palm Pre USB cable also had issues for some reason.
IMO, there should be a sticky posted in this board regarding the packaged USB cable, as I encounter this issue quite a bit.
Ok I'll try to find a new one really quick thanks
ugh tried an HTC Mytouch 4g usb cable and that didnt work either. Gonna try a class 4 usb stick and im gonna try puttting all of the files on the computer from the SD card
Edit: Oh wow i cant put the files on the computer duh
Edit: Ok now I'm mad a Class 4 SD card wont connect to the computer thru the epic ughhhh
I'm guessing during this time, you've rebooted the computer a few times? Sometimes, that's all it takes...
Try uninstalling ALL of the USB drivers associated with the Epic, rebooting the computer, then connecting (with debug mode OFF). Windows found and installed the USB drivers for me in just a few seconds when I did this [with the new cable, the first time].
- G
Have u enabled development mode under settings > applications (in your) epic? If not, try that, then plug in cable.
Then pull down the notification bar and it'll give you back the option.. again, if you haven't tried this.
On occasion I have troubles with the Epic mounting/ejecting on a Mac, but the only time I've ever had an issue with it mounting on a PC a different cable solved the problem immediately.
Try a different USB port on your PC. If that doesn't work, try rebooting the PC and the phone.
I had luck with trying different usb ports though
I had this problem as well and:
1. Tried 4 different cables
2. Tried all 4 on all 4 different USB ports
3. Rebooted numerous times
4. Uninstalled/reinstalled drivers
5. Tried 3 different PCs (1 other running 7 and another running Vista)
6. Did 1-4 on all three computers.
OH! and the reason I was so adamant about finding a solution was that I was stuck in Clockwork... due to having messed up an EXT4/RFS/CW2.5/CW3.0 installation... It was MY fault... I screwed up.
The problem was I had been living with the nonmounting problem by simply putting my MicroSD into an adapter and plugging it into my Laptop for file transfers... never expecting to HAVE to ODIN at some time...
Anyway... I ended up coughing up the $100 to Insurance and replacing the phone.
HERE IS MY THEORY: I think what my problem was was that the USB port on the Phone was messed up. I think these USB ports are possibly a hardware fail point and the changing of cables has been a patch on the issue with the port... NOT the cables themselves!
I'm not suggesting that you are there yet since it sounds like you can at least still get the phone to boot up (and aren't stuck in CW) and could still use a work around of putting files on the MicroSD with an adapter...
But I would suggest you don't be as stupid as me and get yourself in a position where ODIN is your only hope.
Yeah, it sounded like a bad USB port to me. Also, FYIY, if you ever have to replace the phone through insurance, tell them that the phone was lost. Either way, it will cost you $100.00 to get a replacement and when it's reported as lost, they will also send you a new battery...

Let me start by stating that I have read through pages of various threads on here & haven't found an answer... Or at least I haven't found an answer in laymen's terms that I can understand. So, if/when offering help, please break it down for me a little. Thank you!!
I just purchased a Nexus 7. When I plug it in to my Windows 7 PC, nothing happens. It doesn't install any device drivers. It doesn't appear anywhere in my device manager. Nothing. After reading several posts, I downloaded drivers from Asus's site, but now I don't know how to install them. I came across this comment from "MrTrackZed" in another thread (one I can't yet post in):
"After you download the driver, unzip/extract its contents. Then you go to your device manager on your PC, and plug in your Nexus. You'll see it with a yellow exclamation point, right click it and select update driver. You can then select this driver manually. Also, if using Wug's root method, make sure you configure the fastboot driver as well. I don't have my PC with me, but I believe its step 6 in the driver install process. Its all very easy, sounds confusing, but its not. Good luck! "
I totally understand that, but what do I do if the device isn't even showing up in the device manager? I've plugged it in to 3 different computers (2 windows 7 & one Windows XP) and it does nothing on any of them. The device does show that it's charging, but nothing else. Please help. This is driving me nuts. Oh, and I've done all of this while having debugging on & off. Same results.

U may just have a bad device! I have seen posts similar to this and after a device exchange they have no problems.
The fact that It doesn't register on three different computers means that or a bad cable.

When you plugin your phone, on your phone, you need to click USB Storage, did you do that?
Another thing to try is to enable Debuging on your phone, and install drivers, to check if device manager can detect it.
We have a package contains the right drivers for your device, you may want to download and try it. We have Nexus 7 users works fine.

This is for our vmlite vnc server, but it may help you, as it installs USB drivers.

It just occured to me that some USB cable is charging only, this morning, I got such a cable, there is no USB device showing up in device manager with that USB cable, once I switched to another data cable, it works.
You may want to change to another usb cable to test.
Problem Identified
Okay, so after much research, I think the problem has been identified. The one thing that I've found in common with all the threads that discuss this problem is that we've all, at one point or another, used a USB car charger to charge our N7. I've found that most cheap USB chargers only put out at about 1 amp. The N7 is trying to pull 2 amps. This is causing the USB cable to overheat & damage the USB connector on the N7. Unfortunately, once the damage is done, it's done. Fortunately for me, I purchased my N7 at a local retailer that had a 30 day return policy & they gave me a new N7. It works great & I've ordered a 2.1 amp USB car charger to prevent this from happening in the future.

Thank you for the reply, but I am using the OEM N7 USB cable. Plus, I used 3 other cables to no avail. See my previous comment though. I've identified the error.
Sorry for the bump, but are you saying that (under)charging at 1A essentially breaks the N7? Wow. You'd think it would break if you'd feed it 5A or so, not at less than 2!
I think I'm having the same issue now. I can charge, but no debugging for me since my computer doesn't even notice a USB device. Must have happened in my car once when I was trying to charge my phone and my N7 at the same time. (Since then I can't charge any phone at all in the car using that charger.) Let's see if I can find the warranty slip.
Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

I do same thing, it is worked in another computer.
I am already put fresh win 7 but still same problem..
im on xp(retro yeah ha ha) but just a pc i have for my phones and stuff. But i got it working again by flashing my firmware through odin and its back working. Im blaming when i rooted it that it broke but ill see if it happens again
edit: Can confirm pc is now picking up phone. I just flashed the most recent stock rom for my carrier through odin and as soon as it finished updating its prefect now. Might wait another while to root it now and wait for more devs to jump aboard for more roms

I'm on stock, no root.
Hi
I don't know if it may help but i noticed the usb doesn't work when the phone is locked.
I did check 'stay active while charging' in dev parameters and i never got disconnected again.

Tested it out on a fresh copy of Windows 7 and it still continuously disconnect. What gives?

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.
It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.
Any way to connect in master storage with out root.

Use a different usb cable and usb port. I know it sounds stupid but there has definitely been phantom problems which were solved this way, even with something as simple as adb commands
i have same problem. trying all the way but always with the same result...
