usb mass storage

hi, mates
i faced with a problem on my hero,
it doesn't connect to PC.
after cable's plugged in, sometimes I see mode selection dialog, sometimes - no, but in any case, PC writes : usb device is not recognized.
sometimes i see removable drive win explorer, but after clicking on this windows tells me - please insert disk into this drive,
and hero detaches mounted drive with notification about preparing sd card for usage.
i faced with with problem not after next flashing custom rom, but after that i tried to wipe data and flash various roms, the same result.
how do you think this is hardware issue? or recommend me to try another steps to fix this, please

use usbdeview to remove anything HTC then reboit,don't let windows install anything from Windows update

Thank you,
I've tried this solution,
but it doesn't work completely.
Actually, I've tried to connect my Hero via usb with XP, Vista, Ubuntu, OSX
and got the same problem,
host loses the connection to hero,
sometimes host can't connect after plugging cable ,
sometimes host can transfer small files, but when I try to copy large file to the device and host loses connection during the copy process.
looks like a problem with usb connector/controller on device side,
like power trouble, low voltage on usb
your opinion?

Usb problem

Hello! (first post , have been reading for a while though)
I can't connect the phone to my PC (win7 64bit), not as a mass storage device or with Kies (it worked fine before with my home PC and an XP machine at work).
It stopped working after the PC said "Device drivers installed properly" (or something like that) when I connected it, after that I have'nt been able to make it work as mass storage device on any computer..
Very strange and very annoying!
I'm thinking I might factory reset the phone (would very anti-nice though to loose all apps and stuff), so I thought I'd ask here first if there are any possible solutions..
Thx!

if you open device manager in Win7 x64 do you see it listed as GT-I9000 in Portable Devices ?
that's what it shows in mine, and i'm on x64 Win7
it automatically opens in Mass Storage also works in Kies

WEE!! Got it to work just now!!
Rebooted the phone (as I do every day) and connected it to charge over night, and windows popped up with the "installing device driver blabla dialogue" and suddenly it works!?!
This after not working for at least a week on any computer...
I have no idea what might have caused it, but I'm just happy it works again
Still, very strange...
It shows up in the device manager now, it did'nt before.. Thx for the reply!

On Win XP
is there a certain driver i have to download before using USB Mass Storage option.
all i get are two removable drives icon. but they can't be opened

you should only have 1 removeable device icon, 2 if you have a micro SD card inserted.
if you configure the phone to ask you what to do with the usb during connection, then you can select Kies or Mass Storage
regardless both works fine

i do have two removable drives because of the addition of the sd card
its set on Mass Storage. but it still won't open. im not sure if Windows installed it properly though
the driver details:
driver files- system32\drivers\USBSTOR.sys

does it shows in device manager, as mentioned above ?

After connecting the phone via USB, did tell the phone to Mount the drives?

anyone else encountered this issue?
Is anyone else having trouble connecting their Galaxy to a PC? I don't know whether mine is faulty or not. Downloaded the Samsung Kies software but when I plug in the Galaxy Windows is unable to find a MTP USB device driver and the phone refuses to connect. This happens Windows 7 Home Premium 64bit. Also the Galaxy has a complete fit and keeps flashing between the home screen and MTP application screen while it's connected (wxw.youtube.com/watch?v=R9hdpJPCP-k). And I don't get the usual Android option to mount for file transfer. Am I missing something?

finally managed to fix tis stupid kies connection problem...if anyone encountering the same issue jus do a factory restore n format ur internal sd card

PC Does Not Recognize My Device

Hi,
I have a strange problem when I try to connect my device to the PC.
After I installed Kies for the first time, the PC recognized my device one time. After I had removed the USB connection, when I try to reconnect the device, the PC did not recognize it.
I tried to reinstall Kies, install drivers without the Kies, I rebooted my PC everytime - nothing worked, it still did not recognized.
The only thing that work is a System Restore which I did on my PC (for before I installed Kies for the first time), but then I got the same problem - for the first time I connected my device after the Kies installation, the PC recognized my device, but after I unplugged and reconncted the USB cabel, the PC did not recognize my device, again.
Meanwhile, my System Checkpoints on my PC where deleted (I guess because of the System Restore), so now I can not go back to square one again.
I tried to find identical problem in the forum, but I did not find one.
My operating system on my PC is Windows XP, 32bit (I do not have access to another operating system, surely not on a daily basis. If it is necessary, I will try to find a computer with another operating system).
The Kies version which I installed is 1.5.3, the most updated as of 31/10/2010, downloaded from the official Samsung website.
I do NOT use LauncherPro, or any other launchers for that matter (I only installed a few popular games, from the market, on my device).
Thank you!
Yuval.

Try removing any media which might be there on your internal sd card. If that doesn't work then try and format the internal sd card. Certain apps like winamp too prevent the phone from connecting to the pc. It sure did work for me. Hope it does for you too.

I did transfer some .mp3 and .wma files from my PC to my "media" folder in my device through Kies in my first (and successful) connection.
However, deleting them (+ reinstallation of Kies + rebooting of both my PC and my device) did not help, and my PC still does not recognize my phone.
How do I format my internal SD card?
Thanks!

if you have any other devices like printers, external hdds, etc connected, remove them and connect your phone.

Go to settings, sd card and phone storage, internal sd card. Unmount internal sd card and then format.

The only devices that are connected to my PC are the screen, mouse and keyboard. Should I remove and reconnect them?

Do you get the usb connection sounds when you connect and disconnect your phone to/from the pc?

It is all OK now .
The problem was two bad USB ports. It took my some time to cosider the posibility that both of them do not work well. Using a third USB port fixed the problem.
For all of you - if the phone uploads the "Kies" screen (the blue one) when connencted, it is probably the USB port or the USB cabel to blame.

[Q] Verizon USB

Recently, I installed a theme incorrectly which lead me to factory reset my phone. I am currently trying to install dl09 but I can't seem to get into my SD card from my computer. When I plug the usb into my computer + phone, it pops up a window "CD Drive (F Verizon Mobile" instead of the usual pop up for my SD card. In the folder there are files to install Samsung usb drives but I don't need them so I just click exit. I'm assuming this is getting in the way of getting to my SD card and even though I install the drivers using Verizon's files, it keeps giving me the popup. How can I solve this issue? Thanks in advance.

Try rebooting the phone while its plugged into the pc, that usually works

With DL09, that would happen to me, but all I had to do was wait a minute or so and the CD-ROM device would unmount and then the standard USB Mass Storage device would mount and the USB would kick in on the phone. No, really, that's not a joke
I also found that with both DL09 and the leaked Froyo, setting the phone USB to Ask on Connection worked better than arbitrarily setting Mass Storage for some reason.

My phone has started doing this after installing DL30, but I found that if you right click on the cd drive and click eject, your phone will then display the mass storage pop up and you can mount the sd card as usual.

Tried rebooting while phone was plugged in, no luck.
Waited when phone was plugged in, popup did not disappear.
Right clicked and ejected the F:\, still no luck.

Have you tried enabling USB debugging under Applications->Development? This fixes the issue for me on DL30.

usb drive not recognized - help please :(

Hi
I've been using my Galaxy S as usual but today the phone/computer wont recognize it's connected as mass storage or kies.
There is no option on the phone to mount as it did before , all that pops up on windows 7 is usb drive not recognized
I searched on google and tried various things such as :
-USB debugging on and off
-Removing battery
-Trying different cable
-Trying different computer
-Factory data reset
-Formatting internal SD card
-Switching Laptop on + off/restarting
-Uninstalling/reinstalling drivers + Kies
I use the standard launcher and havent changed anything up to the point when it was working.
Does anybody have any suggestions. Im pretty sure its still in warranty however i purchased new on ebay last year so im not sure how all this warranty stuff works.

Do you use an external sd card? If so try this: put it out, turn phone off and on and try once more to connect

Yeah i think your external sd is ether corrupt or broken. i bet if you leave it out completly the phone gets recognized as it should.
Save your external sd data on pc (if you havent already) wipe your external sd and see if it works
If not you unfortunately have to buy a new one, at best from a different brand.

Did you update your firmware recently? I updated from 2.2 to 2.3.3 and it has a few issues, including not being able to connect as mass storage yesterday (though I had no such issue for the past few weeks).

Firmware was updated to 2.3.3 in may but haven't had any such problem with it until now
After trawling google some post said that they switched on their bluetooth connection and then connected to mass storage and hey presto i did this and all seems to be working again. Seems very strange but for those of you who stumble across this thread.
Switch on your bluetooth and then connect the usb cable.
In my case it connected without issue.
Switched off the bluetooth and tried and it connected without issue...so it could possibly something to do with bluetooth who knows?
Appreciate everyones input thankyou

Hi!
I have the same problem. Windows can't recognize my phone, even in download mode.
I have tried the bluetooth on-off trick, without success. I have no micro-sd card in the phone. I tried on 3 pc, and in my Macbook Pro.
Can someone help me?
Thanks,
David
p.s.: Sorry about my english.

Have you tried with other USB cabel ???? I had problem with my USB and recognizing phone on pc, even with instaling drivers :-( (sorry for bad english)

Also been in this situation. Couple of things I learnt:
1. make sure you have a well charged battery
2. fiddle with the usb connection on the sgs: it gets loose and is not always good, press the cable up and see if the pc gives the usb connnect sound
3. uninstall the existing Samsung drivers and then re-boot, then re-connect the usb and let windows find its own drivers or install the latest Samsung drivers posted here (http://forum.xda-developers.com/showthread.php?t=961956) -- but that guide also says, reboot the computer after installing the drivers prior to trying to connect the usb again. Its a windows thing: you must reboot after either install or uninstall the drivers.

Most probably it should be the USB cable, there is something wrong with your cable/port.

I had the exact same problem. I took my phone back to the dealer where the manager messed with it for half an hour. In the end he got it working by removing the sd card and power cycling the phone 3 times removing the battery each time. Presto, I haven't had the same problem since.

Sometimes a very careful tweak of the pins in the port can help, and it is not unknown for the soldering to be cracked, so both worth checking also a clean with a suitable cleaner can help
