Hello, from today every time I connect the phone to the pc i got the following error message "usb device not recognized"
I tried on several PCs, activating and deactivating the "USB debugging" mounting in recovery and also in download mode, the same error.
this error comes after a blue screen windows caused by a virus.
fortunately charging works, but what can i do? Cause i cant connect to odin too,
Recovery, download and rom are three separate operating systems, to have the same problem in all three would be very unusual. Have you tried a different usb lead, usb OTG, or MHL functions? All I can suggest is factory reset the phone.

Yeah, so i've read plenty of topics about USB problems, but none gave me the
anserw.
I'm running Villain ROM 3.0. I just cant connect my phone to the computer (Mac).
It work well before also after flashing Villain.
What i tried:
1. connecting my phone without usb debuging ->phone gives the sound and report in the notification bar : "MTP - initializing" then "USB Connected, MTP-connected" But it does not gives a connection with my mac.
2. Connecting my phone with usb debuging ->phone gives the sound, but nothing happens. nothing in the notification bar neither on the computer. It's strange becouse before it was making the same sound and giving me the info in the notification to connect.
3. I've also tried KIES air it works fine. i can see my phone content, but when im trying to send one file (130mb) there is no reaction to this.
Also some time ago i was able to get usb working by simply choosing usb debuging and restarting phone.
But now i have no acces to my storage
Please help
I have a similar problem.
When I connect my SGSII to my PC (with USB Debugging On) I see 2 Removable Drives in Windows' Explorer. If I click on either one I get the "Please Insert Disk". If I connect to the same USB with USB Debugging off, then Kies Starts but does not connect.
Now the weird bit, if I do the same thing in the next USB port, then everything works fine.
Going back to the first USB slot then the problem reappears.
The 2 USB slots are next to each other and go back to the same controller on the motherboard. I have removed Kies and reinstalled Kies. I have uninstalled all the drivers. I have even changed the USB cable. When I plug a USB External Hard Drive into either USB, it works fine.
Maybe the phone just likes the one connection per computer. I'll have to test that out in my work's PC.
Update:
managed to get a microUSB cable and tested it on my work's PC. Exact same situation. Both PCs run Windows XPpro.
Has anyone else noticed this?
Now, when you said that, i checked with my second usb por, and everything works fine .
So thanks for your help. One working with sgs2 usb port is enought for me
Hi, I have a Galaxy Player 4.0 that I rooted with SuperOneClick. It was working fine at first then a couple of weeks ago, I noticed that my PC no longer recognizes it as a device, it just charges when I plug it in. So, I looked around andn tried a few things:
Restarted it several times
Tried with all the different modes in USB settings
Tried with different cable
Tried with two other computers, a Mac Mini and a Win7 laptop
Tried to unroot, couldn't get that to work
Did a factory data reset
Nothing works. I can't remember anything I did since rooting that would cause this, except I installed the Samsung Kies driver on the PC. I can't remember if the USB mass storage was working after Kies. Does anyone have other ideas?
Bump. This is rather a big deal, as I cannot transfer files between my PC and Galaxy player in any way other than over WiFi, which does not work reliably. I don't have a microSD card adapter either.
You might want to check if anything related to samsung/android appears in the device manager. Alternatively, to use heimdall I use Zadig to switch from samsung's driver to libusb but it does show you everything connected to your computer via usb when you check the option to list all devices. You should try this with and without usb debuging enabled. If nothing shows up you know it id your player that is at fault.

Thanks,
The first time I plugged it in without USB debugging enabled nothing showed up, when I enabled USB debugging, in Zadig and Device manager there showed up an unknown device, trying to update driver in Device manager showed that it already had the best driver, and in zadig driver replacement failed. Now, when I plug it in, either with or without USB debugging enabled, nothing shows up anywhere. I have tried with other computers and other cables, and nothing works, so I am pretty sure it's the player. I am willing to to a complete factory system reset, but I don't know how.

I'm having the same problem with my rooted 5.0. Although it's not a huge problem for me (I use dropbox for file syncing) I would love to sort this out, let me know if your factory reset works!
You can find it in the Privacy section of the settings menu.

I suspect you have a faulty usb connector on your device, but it doesn't hurt to do a factory reset. But you might want to backup your data first Did you try to jerk the usb cable in your player? A loose/broken connector would explain all your problems. Even if it is a software problem, I can't see how to flash your device with the original firmware since you don't have a sdcard & usb doesn't work...
Btw, I was referring to zadig only to show the devices attached to your computer, not to change the driver!

Thanks, I only tried to change the driver because it showed no driver already installed. I have a bit of electronics background so I may crack it open and take a look at the connector. I already tried the factory reset in the privacy menu, but that only wipes data apparently, not the system. I do have an sd card, I just don't have an adapter to the PC.
EDIT: After wiggling the cable around a bit, it showed the USB icon in the status bar, so I clicked connect USB mass storage, but the computer still showed a badly installed driver and then after some more wiggling the icon disappeared, so I am pretty sure it's a problem with the connector. BTW, how would I flash the stock firmware to unroot?
Hello xda users,
I'm having a really strange problem. When copying files from my PC to my phone (be it the internal storage or the SD card) the window that shows the transfer process just hangs and nothing happens. Example: see transferhang.png from attachments (sorry, can't post links yet)
After leaving it "copy" for a while I get this error:
see cannotcopy.png from attachments. (The error says: Cannot copy item: the device has either stopped responding or has been disconnected.)
I am running Windows 7. My Galaxy SII is rooted and I am running the MIUI rom. I have searched around and have found no working solution.
However, if I change the USB port from the front of the PC (USB 2.0) to the back (USB 3.0) I can transfer small files like photos but larger ones (like 150MB for example) hang up.
Copying files from the phone to the PC, however, works. I find this whole thing really strange.
If anyone has any idea as to how to fix this please tell me.
Did you try the same thing on another computer?
Did you try to change the use cable?

Tried it on another computer, same thing.
Haven't tried another cable, don't have one.
Did you face the same problem before the MIUI rom? Sometimes the ROM could cause the problem

Running stock android (4.1.2) I did not experience the same problems, but I had other issues.
While on stock 4.1.2 my computer couldn't detect my device for some reason. It always failed to install the drivers and the "Troubleshoot connection issue" option in Kies did nothing. Every time I connected my device to the PC I got a "Device not recognized..." pop-up. I was able to get my PC to detect the phone but I had to do really strange things (strange as in I have no clue why it works) and it didn't always work.
What I did to get my PC to connect to my phone was:
1. Open settings
2. Go to USB options
3. Choose "Mount USB storage" (most likely not worded this way)
4. Connect my phone to the PC
5. Get a "Device not recognized" error
6. Go to developer options -> Enable USB debugging
7. Boom, it works. (but as I said not 100% of the time)
While doing all of this I had Kies running, otherwise the method doesn't yield anything.
I tried just enabling USB debugging and connecting the phone, but it didn't work that way. For some reason the only way to get it working was to mount the USB storage and enable USB debugging after that, all the while running Kies on my PC.

Currrently Im using Neat ROM for my GS2. I have kies totally uninstalled. I plugin my phone to the pc and it recogonized it. I have the USB debuggin set on. You can try to install another ROM tho, and make a full wip etc. I cant tell u that getting a new ROM will 100% solve your problem, but you can give it a try tho.
/Amiroslo
I have tried doing a full wipe and it doesn't help.
The only roms I have tried are stock 4.1.2 and MIUI.
I can't tell whether it's a Windows problem or a problem with my phone.
Try new stuff
Either
Try a new Rom, stock or aosp or aokp
update your usb drivers, just google and you will find the new one
Got a new cable. Worked.
I have been running on Cooks I777UCMD8 rom for about 2 months now and have had multiple powering issues. Have tried all the basic trouble shooting, not sure if its the Rom causing the issues or the AJK noswap Kernel, but nothing has been tweaked, running as is. The booting issue is when connecting a USB cable while the phone is powered off, if you try to turn the phone on while the USB cable is still attached you get a POWER RESET OR UNKNOWN UPLOAD MODE error message, only way to avoid it is to remove the usb cable and hold power button then it powers up normally.
now the problem with the USB cable, and i feel these two are possibly related, my phone no longer recognizes when its attached to a computer usb hub, it charges, but dose not enter into mass storage mode, nor does the computer recognize that the phone is attached, i have tried on multiple computers with same results, and yes all drivers are downloaded on computers. Further information; Before this problem began accruing, I would get error messages after attaching the phone to a pc VIA usb cable saying ( ONE OF THE USB DEVICES ATTACHED TO THIS COMPUTER HAVE MALFUNCTIONED, AND WINDOWS DOES NOT RECOGNIZE IT ) also, after plugging in the usb cable and windows attempted to download the drivers this error also appeared ( DEVICE SOFTWARE WAS NOT SUCCESSFULLY INSTALLED, CONSULT WITH YOUR DEVICE MANUFACTURER FOR ASSISTANCE ) it later resolved itself for a short time ( couple days ) but now when i connect the phone, nothing happens... i'm hoping somebody has had similar USB problems after flashing a new rom and knows whats going on.
additional information:
- i have two Galaxy S2 phones both running cooks-i777ucmd8 rom and both phones have had the exact same issues.
- previous problems also include boot looping, and frozen lock screen upon powering up the phone. has not happen in a while.
Hi,
maybe one of the experts can help...
I have a LEMAX2 with X820_20S_ROW_CUOCO92 ROM.
Since half a year or so the USB-Connection to the PC does not work anymore. Tried several cables and several PCs, no change.
I can boot the phone in RECOVRY Mode, but it It shuts itself off immediately.
I can enter fastboot mode, but the phone is still not recognized by the PC.
When I connect the phone via MyPhoneExplorerClient, WLAN works, but MyPhoneExplorerClient says 'USB-Cabel 'Not conneced.'
When I unplug and re-plug the USB-Cable, for a short time MyPhoneExplorerClient says 'USB-Cabel 'conneced', but no setting option for USB configuration can be found and after a second or so MyPhoneExplorerClient shows 'USB-Cabel Not conneced' again.
I tried to find out how to change or repair the firmware but all howtos require a USB Connection.
Mayby I accidentaly removed some system software responsible for the USB Connection?
Any idea?
