Hi :
I am having a problem with my Galaxy ACE. Every time i connect it to the computer, i get the 'USB Device not recognized' error message.
However, the phone does charge, either connected via USB or at the charger.
I've already tried on different computers, with different cables, both on Windows 7 and XP, and with KIES installed and not installed.
On some pages, i found that the problem was solved by changing USB and UART to PDA instead of MODEM in the PhoneUtil menu. And that the PhoneUtil menu is accessed by pressing *#7284# . When i press that on my ACE, i get a ServiceMode menu that seems to make diagnostics, but don't let change anything to PDA or MODEM.
I still have not tried if ODIN recognizes it... i will try later, but any help will be highly appreciated.

I had this problem too. Turns out I didn't have the driver for the phone.
I use Linux on a daily basis, and totally forgot that Windows needs driver software for most of its hardware.

What do you need to connect to the PC for?
Make sure USB debugging is off:
Settings-Applications-Development-USB Debugging
Connect to PC, if you still get the message download and install the phones drivers from the Samsung website.
Hi :
I need the USB connection for :
1. Use the USB tetherig to connect my laptop to internet using cell phone data plan
2. Read the SD Card sometimes
I installed CWM4 on the phone.. and flash a custom ROM CM7, believing this was a software issue.. but problem remains the same.
I will try to leave the phone to service next week. But as i had flashed it, i¿m not sure if the provider will accept it as warranty.
Are you using the original USB cable?

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...

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.

Try another cable.

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.
Hello, I'm trying to connect my s5830 to my PC; Phone and computer beep like they are working, but it keeps giving me a "USB device Not Recognized" message. (it does charge by the way)
As per my previous research, this is what i've tried so far:
- On other computers, windows 7 and xp, same message.
- replaced usb cable, same message.
- factory wipe, same thing.
- cache wipe, wont run(?) - maybe this is a clue?
Its running on stock 2.2.1 firmware with no mods, not even extra apps. I actually have another s5830 (from a friend) and it works fine when i connect it to my home computer (windows 7) or my laptop (windows xp)
Any ideas of how to solve the problem? Thanks in advance.
Delete your drivers, reinstall kies and reconnect.

Just tried that, no luck,thanks for the advice.

Delete the usb driver, uninstall kies then restart your pc.
After restart, dont plug your phone to the pc yet. Install kies.
After installing kies, plug your phone and let kies detect it.

Just CONNECT to another USB port.
If its not helping and like I see you have same problem with other PC-s too, then I think its your phone HARDWARE problem. Bring it to SAMSUNG service.

Thanks, im going to take it tomorrow to see about getting it fixed.

I'm facing the similar problem too. Kies on my pc couldn't detect my SGA. N there's no "usb connection" n " usb debugging" icon appear on my SGA. What actually is the problem?
I had this problem after upgrading kies the solution was inside kies under tools there is a install driver option kies then loaded what I presume are newer drivers and it worked
i tried install driver for a few times. the problems remain unsolved! i connect my SGA to pc, the only thing it can do is charging...

Try using any externel drive see if it works.

As per the title, device manager doesn't change when I plug the phone in, tried two different computers and two different cables, flashed the stock firmware back, and still nothing.
It charges when I plug it in and SOMETIMES brings up the MTP-Initialization logo thing, but never gets any further.
Is my GS2 goosed yet again?
Edit: Tried on my PS3 as well and still charges, but won't ask to mount the SD card or anything, so I'm back to my trusty HTC HD2, wondering whether I should sell the GS2 once it's repaired and get a Galaxy Nexus...
Hah, another HD2 veteran, it's like everyone from the HD2 forum is now here... even the devs. Anyway, may be a stupid question, but are you always trying with the same USB cable?
Disable usb debug mode
Sent from my GT-I9100 using xda premium
Tried two different cables as stated in my OP, and it doesn't matter whether USB Debugging is on or off. I'm taking it back to the service centre after work today, and I'm probably going to sell it after.
I've had the camera go.
I've had it not vibrating at all.
I've had problems with spots on the camera lens.
I think I'm going to put some money to the sale of it, and get a Galaxy Nexus, hopefully the built quality will be at least a little better...
Solution is in the phone
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
also
Phone is not recognized by laptop when it is in USB debug mode, MyPhoneExplorer does not recognize when it is not in Debug mode
Hope this helps

thanks people!...even i had upgraded to 2.3.6 and usb mode just wouldnt work....
this solved that problem though..
Fantastic tip!
It worked! Now my S2 can be detected by the PC.
Thanks a million!
Doing a factory reset after backing up data will solve the problems.
Still Hasn't worked for me. I'm getting no USB function other than Charge. Its working as if the USB isn't plugged in at all.
Is there anyway of reinstalling the MTP application on the phone? When i find it through App manager its showing with no size and no options inside (clear data or clear cache)
Kies isn't working as far as the phone is concerned there is no USB connection at all.
I know ICS is coming within a few days for GS2 owners, will this clear the problem???
So frustrating.
Thanks in advance if anybody can help

same with mine. mine still doesnt work with the dialer *#7284# and with debugging off or on. ive unistalled and reinstalled the driver serveral times and nothing and this has happened to me on my hero and my sgs2 dozens of times, its so annoying =[. at one point i manged to get all but the usb storage drivers installed. what else can i do ???
Same problem
Same problem here, tried everything (to my knowledge). Someone told me it had to do with the battery overheating because I had use the charger from another phone. For about 2 days my phone would go on vibrate randomly and started the connection process (like a usb cable was connected). It could do that non stop for a few hours. Now that Im back to my original charger, it stoped, but still can't connect to my pc.
I tried on 3 diff PCs with diff version of windows...
I've tried everythin, debug mode on/off, reinstalled Kies, drivers, did factory reset, but nothing.. when i try to connect my SGSII to Kies, it writes "Current connection mode not supported by Kies".. I'm on Lite'ning rom v2.2..
If you're running a custom rom, why would you want to use Kies ? It's awful. There are so many other apps that have the same functionality as Kies (tho granted not one app that does everything Kies does) that work perfectly with custom roms.
Only reason to use Kies would be if you went back to stock because you wanted official ICS OTA or similar IMHO.
I did a backup with Kies, now my all contacts, sms, videos, music, calendar are in this f***in' backup file.. :| I have an awfull headache Or i can do a restore with another app, will it be compatible with Kies's backup file?
same problem. USB connection to PC will only charge. Recently updated to 2.3.6.
Tricky one.
----------EDIT---------
it worked ok after rebooting my PC. Must just be general crapiness.

Won't work on my samsung galaxy s2 (ICS 4.0.3) - windows Xp (sweet)
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.

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!

try installing/updating KIES on your computer. Disable USB debugging from phone settings. then try connecting again. Launch KIES and see if the device is recognized. You havent mentioned if you made any changes on the phone from Stock ROM.
Also check windows update...for any driver downloads
At least you could tell us that you solved your problem

First make sure you have proper drivers installed
install PDAnet and select samung. Now connect your s2
if it still doesnt install the drivers, its the fault in the computer because if it says usb device not recognised, then its his fault
try in the backside usb ports --> worked for me one
or power off your PC and remove the plug and wait for five seconds and then turn it on (im mean power it on )
now you should be able to connect your device
