Morning all.
As of yesterday, my S2 won't connect to any pc in mass storage mode.
At first it connected as it should, but after about 5 minutes - before I'd transferred anything - I got a message that windows couldn't recognise the device/driver installation unsuccessful.
Since then I get this message immediately, have tried 4 different pcs.
Would seem the USB drivers are FUBAR somehow, but MTP via Kies works, as does Odin.
I've tried a full factory reset/reinstall, previous backups - stock and custom - removed, reinstalled and updated Kies, cleaned the USB port on the phone - nothing doing. Have tried stock kernels, Siyah, Nimphetamine - nothing. Currently on XWKL1, custom ROM (krinyo's SlimROM) with Siyah 2.6.3+
Also tried uninstalling various USB ports on my home pc, but stopped when I discovered it was the same on all pcs.
It's not the end of the world - I have bluetooth and my microSD - but it's a PITA and I'm out of ideas.
Many thanks for any help/suggestions.
Have you cheched if USB Debugging is enabled or not?

Yes, forgot to add that, sorry. Tried with and without, no difference.
Tried changing the usb cable?
From another post
Dear All
Following are my observations and possible steps to
1. When the phone is upgraded to Android 2.3.4 and above (mine is 2.3.6) Kies stops recognizing the phones and USB connection / Serial port connections etc get reset on the phone
2. Even if proper drivers are there on the laptop (mine is Windows 7 64bit) they are not recognized
3. Device Manager shows "unknown device"
4. Updating the driver also does not result in any help
5. solution lies in the phone
a. key in the dialer *#7284#
b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect (thanks to napi1 @ androidforums.com/samsung-galaxy-s2-international/447145-sgs2-kies-not-syncing-os-2-3-5-a.html#post3484588)
6. The Laptop will start recognizing the required drivers and install them

Getting a Service Mode FC when I enter that code in the keypad.
Will try it with an older backup.
Edit - tried it with a backup of CheckROM , 2.3.6. No FC, PDA already selected. Tried 5c above, still no good - unknown device on pc..

No. Can't see that there's a problem there if Kies and Odin connect OK.

Bugger me, it was the cable....
Bought a new S2 yesterday - nice to have a backup, and the Nexus is meh - and tried the new cable on old S2, everything fine. Old cable on new S2, no good for USB but fine for Kies and Odin as mentioned before.
No idea why it should be like this, but sh*t happens. Easiest solution is often the best!
same problem happened to me too
I have the exact same problem, tried everything like OP, even new cable still same issue...any ideas?

First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use

I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

I have tried uninstalling driver and just plugging in with USB but still neither PC nor phone detects USB connection.
I have tried it on Win7, Win Vista and WinXP.
respected mates please help me.
I am on transfer in June so don't want to take chance with Service centre as of Now.

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.

Ok, It got solved yesterday this way:
You do not need to reinstall drivers on PC.
You do not need to reinstall ROM or anything on your phone.
You do not need *# special codes.
You do not need a new cable or change USB port or change your phone for a new one.
It seems to me that somehow (probably for debugging, connecting and disconnecting several times) the phone locks itself in a state where it is unable to connect again through USB although it charges.
So how did I solve it? I executed this actions several times even in different order some times: disabled debugging, disconnected cable, restarted phone, connected cable, (still not recognizing), tryed to USB Theter (even when the option was disabled), reenable debugging.
Out of nothing i noticed the USB icon was there again in my phone and i was able to debug copy files etc again.
I tried disconnecting and conneceting again and it kept working correctly.
I hope this helps someone else with the same problem and probably someone fixes the bug on the OS.
Cheers!
my i9100G cant transfer file to my pc.. when i connect the usb, my computer said fail to install and cant do anything about it.. i even tried open kies also cant detect the phone.. i did everything like untick/tick usb debug.. and my phone is DZKJ2 firmware 2.3.6.. any solution? before this i tried to root my phone but i mess something up so i quited it.. is this the cause for this problem?
Try installing the latest samsung kies available. It will come with the required drivers. What OS are you using ?

i'm using window 7..
You said that you tried to root but quit.Hope you didnt try to root with a i9100 kernel on your i9100G cos i dont think they are compatible.Re-install the latest version of kies and if that doesnt work then re-flash your firmware and try again.
well... I have this problem before, me just trying using other port the problem was sloved... (tips: do you unlock you phone before connet to pc?)
Other answer from other forum
Fist:
I) restart you pc,
II) on you kies
III) turn off you phone
IV) connect to pc
V) got driver now?
if still cannot.. try
a) wipe data and cache on recovery mode,reboot and try connet to pc agian. (warning: make sure backup you phone fist)
Hope this will helping you xD
by the way.. i did tried to root my phone.. but end up failed.. so i cant do stuff like flashing.. those rooting step for is was too hard for me to understood..
To fix this problem (Your Windows 7 PC Not recognizing your Galaxy S2)
1: Try another USB Cable (my original cable doesn't work, a generic one I had does)
2: My Computer Properties - Device Manager - Uninstall EVERYTHING from the Universal Serial Bus controllers list, then restart. - This fixed the issue for me, my external keyboard and mouse stopped working but I'm using a laptop and once I restarted everything works fine
3: Update your phone's baseband radio (I was on XXKI1 and my PC would only recognize my phone when I was using VillainROM, nothing else, until I updated the radio to XXKI4).

tried too but isn't really working..
What root method did you try?
I think you can try by type
*#9090# and select "via UART"
then type
*#7284# and select "UART MODEM" and "USB PDA"
Connect your USB cable and it will auto download the new driver to your computer.
p/s: Need internet connection
sorry all.. finally fix the usb thingy.. i think the problem started with the update i download from samsung.. after i download the DZKJ2 firmware.. my pc unable to detect my phone.. now i switched back to DZKJ1 firmware and now its fixed.. though some function may lost but better than nothing.. thanks for your answer too

Hello,
Im trying to flash my phone but having a issue
So i have added the insecure kernel but when i try and do the next part (Run S2 Root) i get the following error
Device is not connected! Please connect the USB cables and try again
Im running the following
S2 Root 1.5.1
Android Version 2.3.6
Kernel Version I9100XWKJ2
Anyone able to help its annoying the hell out of me have tried different USB ports get the same issue
Make sure samsung drivers are installed, try different USB ports, check USB debugging in settings.
If it doesnt work again, try it with a different computer if possible.
Ok when i turn off USB debugging on the phone the PC will connect to it. When it is on it wont?

That needs to be on, so the problem is elsewhere. Did you install samsung drivers, if you did, have you tried different USB ports?
I have downloaded the drivers and still not working
Still cant get it to work
Try this:
http://forum.xda-developers.com/showthread.php?p=18805560
Read the instructions carefully though.
Details : CM7 latest nightly with Siyah Kernel v2.6.12
Symptoms : My PC previously recognizes my phone without an issue (with the exception on when i flashed CM9), I then flashed back to CM7 it was working initially, now my PC does not detect/recognize phone (either nothing happens besides charging or states phone is an unknown device, the latter only happens like 1 out of 20 tries, as it is installing the driver SAMSUNG_ANDROID, it says device suddenly disconnected) even in recovery, Odin can't detect phone. Phone still charges as normal. Phone at times (subject to whether PC states the device is unkown) says there is a USB connection, and still maintains it eventhough i have pulled out the USB cable.
I still am able to transfer files to my phone's internal SD via Airdroid.
Remedies tried : Different PC Port, different computers, cleaned registry via CCleaner, reinstalling Kies & drivers, trying a different Rom & Kernel, cleaning phone's USB port.
Any advice guys? what other possible remedies there is? or is this something besides a USB problem?
Have you tried flashing original firmware to see if the problem persists?
