USB device Not Recognized

Whenever i plug in my i9000, it just pop up an error msg ÜSB Device not recognized. I'm trying to get Kies to recognize my i9000
I tried following this but it doesnt work at all.

it worked for me on kies, but i didn;t like it anyways
What i did was go to settings --> about phone --> usb settings
and try the other options (i'm using media player option, not sure why mass storage doesn't work)

Did you try to change the usb ports on your pc (stick the cable into different usb ports)?

changing the usb port does help, however when i unplug it and restart my com, it does not recognize it anymore

What OS are u running?

Could also have something to do with the number of irq's on your motherboard.
PC's older then aprox. 3/4 years have less irq's and can have trouble with much external devices

Have a look at this site from HardwareZone.com.
It's heavily populated but you only need to read the last five or so pages.

yeah i am looking at that thread too, however thanks for the link here, good for documentation as well, appreciated

keevy17, u have the phone already? If yes, you could help us resolve our questions in last pages of this thread:http://forum.xda-developers.com/showthread.php?t=694835&page=9
Q: Are there any notifications (on screen, backlight of buttons, ...) about missed calls, new mails, sms? Is there any notification when u charge the battery and the battery is fully charged?
Thanks in advance.

The default USB connection is to activate Samsung Kies. You'll have to go to settings->About Phone->USB Settings to change. If it doesn't work after changing, soft reset the phone and try again.
Caused me a bit of head scratching until I went through the options.

Now am having same problem, can'r see mass storage in my computer.

I think I read you need to enable USB Debugging then it will work. for both of you I believe.

With USB debug i can only use adb, nothing works. If i disable debug i can copy files via MTP protocol but mass storage doesn't work.
Edit.
Found the problem, it doesn't mount it self like Desire/N1 i had mount it my self. All working.

hassan,
I've not yet had a chance to use the phone yet. Can you tell me how you mount the USB in order to use it with a PC?

It was bit tricky to start with as i thought my phone is broke. First go to setting > About > USB Settings > and select Ask on connection. Plug the cable in to the and from drop down notification bar and hit USB connected then you get the option to mount the mass storage.

If you want kies to work with the phone, dont kill MTP.. But kies is acting weird, soemtimes it doesnt see the phone, but after unplug and replug it works again.. I've given up on kies actually, over 100MB to download and worst than some beta software i've used.
also, i cannot get samsung apps to work on kies, it just error or timeout.. you guys hv any luck?

I haven't tried kies yet, i'll try when i get home from work.

Anybody know how to mount on a Mac? I tried changing the USB settings to Mount/Media, no luck. Any help would be appreciated.

[Fixed] USB mounting problem since installing Kies

My Vibrant doesn't connect as a data storage device around the time I started using Kies. My phone is 100% stock beyond some attempts to fix the GPS (which didn't work and returned to stock). I installed Kies to do USB tethering and changed the setting on the phone to ask in which mode I want to connect.
Last week I was having trouble with connecting in Kies mode and tethering. I then noticed that I could only connect to the PC when I selected the phone option for Kies and not as a media player or storage device. I proceeded to uninstall Kies from my PC to see if that fixed the drivers. No go. I tried another PC which has never had Kies on it and also no go.
Here are the symptoms:
1) Plug USB cable to Phone
2) Menu on phone shows: Select Kies, Media Player or Storage
3) Select Storage
4) USB symbol appears and goes through connecting to connected state
Normally at this point the Win7 PC will pop-up with an auto start window asking if you want to open the storage device or transfer photos. In my case nothing appears. I also check My Computer and the phone is not mounted it doesn't appear later. I suspect a phone issue. Is there a way to fix this without doing a factory reset? Reboot doesn't change anything.

Anyone know a fix for this problem?

Make sure to use these drivers

Stupid question, but are you pressing "mount" on your phone when your in USB storage mode?

note to self: read OP *before* replying
If it's still set on Ask on Selection try changing it to Mass Storage. I recall reading something that said Ask on Selection doesn't work right. I just toggle it between Mass Storage and Kies manually.

Hi happened to me too.
Type *#7284#, so you'll enter PhoneUtil and be sure both the "UART" and the "USB" are set on PDA!

Help!
I rooted my Galaxy 3 and since then i can only connect and transfer data between my phone and my computer by allowing USB debug mode. It used to work without a driver installed on my pc (only data transfer mode like with a pendrive), but now my laptop (which doesn't have Kies on it) doesn't recognize it. I tried it with my TV and it said "unsupported USB device". It used to work as a pendrive but now nothing recognizes it:---( Please help:-C

What he is trying to say, is wich is the default action when you connect the USB.
Example: every time that you connect the USB the phone gets into Kies mode, or Mass Storage.

Cannot Connect to PC AARGH!

Hi,
EDIT * I have found a solution in that I can connect via WI fi so that's pretty good but if anyone can help me with the USB issue, it would still be appreciated. It seems that the Wi Fi connection is more limited as I am unable to view things in explorer *
hoping to get some help using my USB to connect to my PC. I've installed Kies but when I try to connect to my PC it just keeps on trying to connect but never actually does it.
I have looked for guidance on this but keep coming across the instructions to go into 'about phone > USB settings' etc etc. However, I do not have a USB settings in about phone. In fact, there is nothing at all about USB in About Phone. I do have a 'USB Utilities' in Wireless and Networks but all that gives me the option to do is 'Connect Storage to PC'. I have a memory card in my phone.
When I do connect to the USB cable, with Kies open, when windows 'finds new hardware' it keeps saying a problem occurred during installation.
Please can anyone help me out? All I want to do is basically drag and drop some files from my PC to my phone. Thanks very much for your help.

Settings --> Applications -- Development --> USB debugging.

Thanks for that!
It got me a little further. I also unmounted then remounted the SD card. However, when I try to connect via kies I now get the message:
Reconnect the device in Samsung Kies (PC Studio) mode. Current connection mode not supported by Kies.
What am I doing wrong? Do I have to re click the USB settings on the phone before connecting to Kies now that it's installed the hardware on my PC?

Turn off USB-Debugging
Don't connect phone yet
Open Kies
Open the Tools menu -> Troubleshoot connection error
Go through the guide and let it reinstall the drivers.
Connect you phone, and let it connect

The default setting has the USB debugging tick greyed out. When I select it, it asks me if I want to allow debugging.
Do you mean that I shouldn't allow debugging and then connect (after reinstalling Kies) or should I allow it and connect? Sorry for my noobishness, Android is all completely new to me.

You should untick the USB-debugging - Then reinstall drivers NOT entire Kies

OK, it's unticked and I'm reinstalling the drivers via troubleshooting.
Do I need to unmount then remount the SD card before connecting my phone? Thanks for your help btw.

Shouldn't make a difference

Bah, I still have the same problem. It just says that there was a problem installing the hardware when I plugged in the phone.
After reinstalling the drivers, i shut down Kies then reopened it. I then plugged in the USB and then plugged the USB into my phone.
When I first installed Kies yesterday, Microsoft Active Sync kept on trying to activate and ask for a CD. It kept on holding up Kies. In the end I uninstalled Active Sync. Also, I still have Samsung PC Studio on my PC from when I had a Samsung a few years ago. It was one of those old slider phones, not a smart phone. Could that be part of the problem? I was hoping to keep it because it's proved to have the best media player I've ever had.
I just don't know what I'm doing wrong here.

Try without restarting Kies.
What part of the drivers aren't installed? (Check device manager)

In Device Manager, under Portable Devices there's something called Android MTP that has an exclamation mark next to it. It says it's not configured correctly and that 'No driver files are required or have been loaded for this device'. I'll reinstall the Kies drivers now.
Thanks for this help mljjlm
P.S. Now that I've unplugged the phone, the MTP thing isn't showing in the device manager list anymore.

Of course, it's a part of the phone, and it should not be plugged in because they would have to force a reboot when reinstalling drivers (which might sort your problem btw)

Reinstalled the Kies Drivers and then plugged in my phone but got the same problem. It says a problem occurred. Same device now has a problem in device manager. Maybe I should just uninstall everything and restart? Should I uninstall the old PC studio too?

Just try the reboot without uninstalling anything and then plug the phone in when your pc has booted

Argh! Still didn't work! I think there must be a problem with my PC, well, I'll try doing full uninstalls and reinstall it all. I have to go now as well so I'll have to try again tomorrow.
Thanks very much for your patience mljjlm. It has been greatly appreciated

Are you trying to just transfer files back and forth? If so... forget using Kies.
(I don't have a micro-USB cable with me currently, so this is all from memory)
Just remove the drivers from your device manager so it's like your machine has never seen your phone before. Then on your phone enable usb-debugging.
When you then plug in your phone, you should get a usb icon up top on your phone's display... pull the window-shade down and click on the USB connection button. You should get a fullscreen window on your phone that says something like USB Connection with the friendly android waiving.
Now your PC should see your phone as a standard USB mass storage device.

try plugging the usb cable in another usb port on your computer and than try again.

You're using Kies, that's what you're doing wrong. You said in your very first post you wanted to be able to drag and drop some files from your PC to your phone, so use USB debugging (say yes when it asks you) and Windows Explorer.

If you are using a custom rom like Checkrom Revolution you will need to install the kies support from kitchen pro.
Also are you using the cable that came with your phone?
I have found a few microUSB cables that will allow charge and wont allow data transfer like the new ones for nokia devices and some blackberrys.

It worked! The USB debugging thing!
Thanks to everyone who helped me out. The forum said I was limited to 5 thanks per day so if you didn't get one of the thanks I apologise. Thanks very much!

[Q] Lost USB connection with CM10 Nightlies Updates

While my original NC is running quite well with the CM10 nightlies, I have lost my ability to use the USB cable as my file transfer source since leaving CM 7.2.
I now do all of my files transfers directly to the SD card by removing it and accessing it directly via my computer.
I get the following when the cable is connected: "USB device not recognized".
I have tried both Media Device and Mass Storage settings to no avail.
This was not an issue with CM 7.2.
Seems to be the only real issue I am experiencing since I was able, with forum help, to redo my inadvertently updated NetFlicks.
Thanks in advance for any suggestions.

First, don't call the ROM JZ054K, it is CM10. You confuse folks. The problem probably is you have USB debugging enabled. Go to settings, developer options and uncheck Android debugging.

Followed your suggestion and unchecked Android Debugging. Rebooted and then hooked up the USB/Recharge cable. Still have same result with the "USB device not recognized" being displayed by Win7/64 with both Media Device or Mass Storage being selected.
Any other paths to explore on this?
Utilized my ROM nomenclature based on "About tablet: Bulid Number" and will switch to CM10 if that is a confusing issue.

The device id and vendor id are different in the CM10 from CM7, you would need to edit the android_winusb.inf file to include them.

Are you sure it is still unchecked? Did you go back and look after rebooting. You should not have to reboot to turn it off. That device not recognized issue is it is looking for ADB drivers because the debugging box is checked.

Yes, went back and looked and it was still unchecked. Normally reboot when I make any changes but went back and redid your suggestion from scratch without rebooting with same result.

The only thing I can think of is to go device manager in Windows and uninstall any devices in portable devices, android phone and under USB controllers, any mass storage devices. Then unplug and replug it back in, assuring debugging is still of. You should now get messages that things are installing, hopefully automatically.

I'm having the same issue, was using the Dec 2 and now 3 nightly. when I get time tonight I will roll back to Dec 1 since I know it was working there. Win7/Win8 here fyi

Unsuccessful
Tried: "...and under USB controllers, any mass storage devices." This actually allowed WE to show "Nook Color" but when I clicked on it, there was nothing there. The unit did temporarily display a USB connection at that time also.
Again, this was not an issue under CM7.2.
Thanks for your ongoing assist!
Update: Okay tried every conceivable way of deleting some or all of USB drivers under DM and reinstalling. Even went into BIOS and turned down USB 3.0 to 2.0!
Again erratically got the Andoid USB screen temporarily a couple of times but could not maintain it.
Definitely getting a Windows "Code 43" error indicator.

Followup
Went there (http://forum.xda-developers.com/showthread.php?p=34954992) ...did that. Did not work at first, but it did work (somewhat) after I went back in and deleted the three drivers. I was then able to connect and utlilize WE to probe and adjust both emmc and sdcard. Calibre recognized that it was connected but I could not transfer anything directly from it to the NC.
Thanks for all of the help with this. Since I am probably around eight weeks from purchasing my HD+, I will just use the SD card to manually transfer files.
Interesting issue nonetheless!

I plugged my nook into a couple different computers and it was like the computer didnt even recognize something was plugged into the computer, though it charged the nook fine.

Had same problem, I went to settings - storage - then the menu box top right (three dots) then choose USB computer connections.. For the most of the time I just leave mine on Mass Storage -- On the second - I just leave the stock file manager and install any others I use - stock is not a lot of overhead for me to bother removing...
