Hi, I've been transferring some stuff to my galaxy s and now i'm getting this error everytime i attach the USB (USB Device not being recognized). I already reinstalled the samsung USB drivers, uninstalled and reinstalled USB root hub drivers, used a different USB port and restarted both PC and galaxy. Anyone have any idea how i can get my device to get recognized by my pc?
no one's encountered this problem before?
I get this on and off - i'm on Win 7. I tried all 4 ports and my hub and sometimes it plays ball - sometimes not.
I often find if I change the phone from 'mass storage' to 'ask on connection' it seems to improve its chances.
Worth a try.

I tried this as well including turning USB debugging on and off.. no luck though. Only thing i haven't done is format the internal SD, but I dont want to go there unless there really is no chance of fixing this. Any help you be greatly appreciated!

i recently just bought a captivate from a seller and found out mines is doing the same thing havent had no luck getting it connected to pc to mount but does charge on data cable after seeing it has been modded to froyo 2.2 rom but trying to see if any one know away to fix this.
Please can someone help me, I have an LG P970 but the USB port seems to be bricked. The phone charges when connected to the computer but nothing else. When connecting the phone to the computer, the computer does not see the phone and the phone does not come up with any usb connection mode.
For this reason I rooted my phone and updated it to the latest version of Zeus rom, but this didn't fix the problem. The phone still just charges on the computer but that's all it does.
I think the phone USB drivers are faulty or need resetting. Is there any software APK I can download to fix my phone.
Thanks for any help.

lol.Man.You reboot intro recovery -> mount and storage -mount usb(you don't unmount).
You must have the phone conected to pc via usb.Then you will able to acces your sd card
To me it seems more like a driver issue more than your phone usb not working, try installing the latest drivers as DaemonOnx said

The problem is that when I go into '>> mounts and storage' the only option available to me is - unmount. There is no 'mount usb option'
By default I select unmount - to which as you say nothing happens.
Happy to try further options if you have any?
Edit - reread OP, response invalid

You most likely have problem with your pc LG drivers.
Download drivers by finding the link for LG driver on this page: http://forum.xda-developers.com/showthread.php?t=1448803
Install the drivers and try connecting and it will work

Hi thanks for this. However, the link to the usb drivers is broken. I have installed the usb drivers from the lg website and I know they work fine because I have now tried connect a friend's LG optimus black to my computer and the computer and phone both recognise each other. So I know it's not the usb cable or usb drivers on the PC. I have also installed the LG usb drivers on my laptop and spare computer, however again I have the same problem - phone only charges.
When this problem initially occured about a year ago I sent the phone back to LG and they did some sort of software refresh, which solved the connection problem for a few months, but then things went back to the way they were. I then thought it may be a PC issue so I downloaded drivers and connected my phone to the laptop and everything worked well. However, again, a few weeks later, things reverted back to the same problem. The phone only charges on both PC and laptop now.
Hope you can understand my frustration.
Someone must know something out there? How do I fix this stupid USB problem?

LG service center? you've pretty much tried all I would've
Last time I took the phone there, I was told it might have been the phone port software corrupted. Whatever that mean. If I can't find a fix to this I will need to somehow unroot the phone and try to get it back in its unrooted state to LG (not sure if that is possible) else they probably won't fix it.
I'll keep looking,
thanks for your help.
You are using the the proper usb cord. I know I have a couple. The one will charge only.
Yes I am using original cables, I have three of them. They all work on my Friend's OB but not on mine. I am convinced it's a phone software issue. This has happened with three different computers - when you first install LG software on the computer, the phone connects okay for a few weeks and then loses connection, and I can never get it connected again.
When LG refreshed the phone software for me the phone worked properly for a little while and then reverted back to charging mode only.
I need a way of reinstalling the USB software or port software onto the phone itself via some type of APK if such a thing exists.
Maybe a developer here can develop one???
hey man
if you have disabled the "android platform usb modem" in peripherals manager, enable it first (phone must be plugged)

this means it must be the result of an intervention by a third party thing, by yourself, or another program. If you have a kind of a software which manages ports or consumption (on phone as well as on Win), uninstall them, then uninstall all LG drivers, reboot, then reinstall them. if that doesn't solve your issue, you may have to reinstall windows. that's radical, but it should do it
Try connecting the usb while doing pressure between the LG logo on screen and the back of the phone, like squeezing something . I had this issue and it was an internal connector issue....
Check if you hear the "tada" sound in windows or any message about a new device.

Hi, thanks for this, I'm not sure what you mean by "disabled the "android platform usb modem" in peripherals manager". I am using XP. I have had a look to see if there is any software remotely associated with port consumption etc and have uninstalled these and also reinstalled LG drivers. But situation is still the same.
Please note: I have an LG GT540 and this connects fine to the computer. I have also connected another LG optimus black and this also connects fine to the computer. On the basis of deduction, it must be a phone issue, somehow interacts with the computer fine and then fails after a little while. Also I haven't installed anything on the phone itself which might manage consumption or port. The computer has a usb host controller but not sure that means anything useful.
I do agree and have feeling that if I reinstall windows I bet the phone would start working again, possibly again for a few months. This means I reinstall windows on my pc and laptop and hope it all resolves without actually getting to the bottom of the problem.
What I need is another laptop to try this on. If I try another computer or laptop and it recognises the phone. What do I make of everything??? Any ideas.
ps also tried holding pinching usb lg cable as suggested but nothing different.
Thanks for all your efforts.
Further update to this, I installed LG drivers on a fresh dell laptop. Again nothing happened, the phone only charges. I am even more convinced that phone software is corrupt. How do I reinitialise phone USB software?? If there is such a thing.

flashing a new rom, i think it may be hardware issue
I have been trying to connect my phone to my PC and all it does is charge. I can't view any files on the phone or add, move or delete anything. It won't respond to fastboot commands. I've tried it in recovery and bootloader and it won't pick up anything. I noticed this when I tried to update to the new Kit Kat firmware. I am running Windows 7, Maximus 30 ROM, elemental x kernel. And I've tried every combination of sync manager, sync and the HTC drivers and nothing responds.

My first step will be to get a good cable, i had half a dozen of different cables and some work, some don't... finally worked out with old cable from my Samsung
Try using another PC/Laptop ?
I've tried 2 different PCs and my laptop. All were the same result. I have only tried the black htc cord that came with the phone. I will try my other cord when I get home.
I've tried 3 different cords and all the same result
Bump
I've tried 2 more computers and another cord and still no luck
Try useing Total Commander for android and you wont need any cable for data transfers.

When you plug it to your pc did it show that it is installing drivers?
And have you tried uninstalling the htc drivers in your pc and see if your htc one
Automatically tries to install the drivers through windows update upon plugging in?

When I plug it into the PC, I get no reaction whatsoever. When I open device manger, there is no changes. No yellow triangles. No unrecognized devices. I'm starting to wonder if it has something to do with the previous firmware/hboot I flashed.

By any chance, have you tried using a different cable? Sometimes we forget about the simplest/most obvious solutions
I've tried 3 or 4 different cables. I did notice today when tinkering with it, no matter what I do or try, I can not get the MTP box or notification to pop up. I am really starting to believe this is an issue with my phone.
I went and bought 2 more different cables and still the same result. I have noticed that the USB connected icon only shows up if I restart the phone with a USB cable in and it stays on even if unplugged. The HTC sync manager notification comes on sometimes when plugged in. And I can never get the MTP icon or notification.
Trying to return phone to stock but the pc wont recognize it. few days ago it stop fast charging. when i connect it to the pc all is does is charge it.not even MTP. i tried different methods for usb settings on the *#0808# and it still does not recognized. i used all type of usb cables.

I don't know which rom you have flashed prior to your problem with the phone.
But if it was my phone the first thing I would do is to go into recovery and do a
factory reset, doing that just might fix the issue with not being recognized by your
computer correctly.
It might also help to uninstall all the usb drivers and kies from computer
then only install the samsung usb drivers for windows.
Good luck,
Have a happy merry Christmas.
Hi, I have a question. I upgraded to A12 and from then, when I connect my phone to the PC through USB it did not recognize it. I try different USB cables but still the same. Maybe samsung have new drivers?
I tried various USB cables, uninstalled and reinstalled the drivers, in the development options I have USB debugging enabled and the default USB connection option for file transfer and tried on several computers and still nothing. I have no ideas what to do to make the phone discoverable again.
hmmm mine works.. have you checked the USB settings? make sure Use USB for "Transferring files / Android Auto" is selected.
