I had the same problem.Make a back up of your phone
and do a factory reset.

tried installing usb drivers sgain ??
Sent from my GT-I9300 using xda premium

try installing Kies?

Its ok i got it to work. Went into download mode and plugged into my PC and windows installed some drivers, Odin detected the phone just fine. Then i booted up into android like normal but switched to PTP mode, windows then installed the MTP drivers (though it was already installed) then after that all worked well again

Please help...
Im having the same problem. But nothing seems to work for me. Tried everything possible. Re-installed drivers, connected in download mode, installed Kies, reset to factory setting..ALL TO NO AVAIL. I keep getting 'USB device attached to this computer has malfunctioned...' message...

The solution isnt always the same for all users.. Fortunately mine was fixed by a simple driver install. I remember browsing the internet and found out that there is a way to fix it but it requires simple adb commands and the Android SDK.

Optimus T USB issues

I have no idea what happened... I can no longer get my computer to recognize my girlfriends Optimus T to enter mass storage. I have reinstalled the drivers numerous times, but still noting happens. It will prompt me to enter into mass storage mode, but it won't go. It is not listed in "my computer". Any ideas?
Same here, i'm using 2 PC's one XP SP3 and on Win7. Phone is not recognized by the computer, though i installed the drivers correctly... Any suggestions?
What ROM are you guys using? I had similar problems a couple of days ago with USB not being picked up.My solution: reflashed with KDZ and rooted+customrecovery, then everything worked ok after that. I think some of the files get messed up after a while of tinkering with the phone thereby causing the USB detect problem.

[Q] Unknown Device :(

Hi everyone,
i'm having difficulties to connect my sgs2 to a pc.
i have tried it on 3 different machines (win7 64, win7 64, winxp 32) with the same problem:
I works fine when i first connect the phone in download mode. But as soon as i disconnect the cable i can't connect it again. Windows sais that it doesn't recognize the device and that's it. The device manager shows an "Unknown Device" under USB-Controller. And i am not even able to install drivers by manually pointing windows to a file.
as already sais, i have tried that on 3 different machines. I have tried installing driver via kies and via the driver file that is available here in the forums. i have also tried different usb ports.
Any ideas?
Goddchen
EDIT: Maybe this is an important information: the phone connects fine as long as it is running (can be found via adb, logcat is working, etc...) it only makes problem when in download mode...
I had exactly the same issue yesterday on my Windows 7 box. In the end I connected the phone in normal (not download) mode. Into device manager and uninstalled the drivers through there.
Then I uninstalled Kies and reconnected the phone, I allowed Windows to search windows update to find drivers (not that it did as it couldn't find any and reverted to the local ones. Then disconnect the phone, re-install Kies, run the install drivers from the tools menu, close Kies. Run up Odin and the connect the phone in Download mode, low and behold 2 minutes later after a lengthy installation process the phone was picked up.
I tried a number of things but for some reason this specific order seemed to sort it.
Hey,
thanks for you hints. But they didn't work for me.
I found the problem: believe it or not, it was THE CABLE. I went and got another cable and this one is working fine all the time. The other one doesn't... Very strange...

[Q] Connection problems

So when i try to connect my galaxy to the computer nothing happens. i plug it in and it will start to charge but the phone will not have recognized the fact that it is connected to the computer and the computer doesnt even say "unrecognized device" how do i get the phone and omputer to recognize each other?
Did you install drivers for the phone? What operating system are you on?
yes i have. ive tried both osx and windows 7 and i have made sure to download teh drivers for each
Have you tried to connect it in usb debugging mode? (goto settings, applications, devlopment, check debugging mode?
(I dont know of it will help, but it would be the next thing I would try)
And try different usb ports. I have heard before that it can help.
yeah ive tried all of that it and still nothing, the switching usb ports too
Did you restart the computer after you installed drivers?
I would try installing Samsung Kies (from samsung website, GS2 support page). It also installs drivers and fixed a problem I had with connection.
If all these don't work, I don't know what to tell you. Sorry. I am sure someone here with more experience will be able to help.
yeah haha ive done all of these unfortunately and still nothing, thank you for you suggestions though
Kies had an update within the hour of New years (Pacific).
I discovered this morning that USB debugging mode MUST BE OFF for Kies to recognize and connect to the phone. I'm currently backing up my device in this mode right now.
"Kies Air" also works well, without having to worry about any USB issues.
"Droid Explorer" connects fine with debugging turned on. I have to wait until backup is complete to see if it works with debugging turned off.
I'm having USB port issues right now, so your mileage may vary.
Hope this helps.

[Q] PC wont recognize

my phone will not be recognized by the computer no matter what i do. It recognizes my friends i777 just fine in odin and as a storage device so it isnt my drivers. With mine it only makes the connection sound and says device drivers failed to install. I am running shostock 3, philz kernel and windows 7. I have tried everything and i am out of ideas, please help. thanks
Install Kies fresh, install android sdk and update it, reboot, try different usb ports.
Also u have to disable usb debugging and let it install those drivers, enable it and let it install those drivers and boot into download mode and do a regular reboot and let it install those. Always worked for me after following those steps.
If he's friends phones works. Then I think it's the phone usb. My own phone has the same issues but my usb on phone is messed up. Says charging while its not chargin and that happens I get the whole Device not recognize and fail to install. Try cleaning your usb with 99% Isopropyl of the instructions above this post don't work out.

I tried the suggestions.....
I downloaded the samsung drivers correctly because my pc recognizes any other samsung but no matter what i've tried it says usb device not recognized for my galaxy. Im stuck in a boot loop and the only thing i can access is download mode when i plug it in the computer. I can't access anything with the battery in, it just flashes the galaxy logo over and over. Thank you for you time in advance

[Q] USB Only Charging, No Other Connection Types Working

I have been fighting this for awhile now. My phone boots up just fine, and I am able to charge it through USB, but I cannot get Windows to recognize it. I have tried multiple ports, checking and unchecking MTP and PTP in settings, enabling and disabling ADB, and even putting the phone in download mode. LGNPST won't even recognize it in download mode. I'm really not sure what to do at this point. Does anybody have a suggestion? I'm currently running CWM 6.0.4.7 and CM 11. Thanks in advance for any help.

Had same problem with my laptop. I installed the correct drivers but still, nothing. Might want to try a different pc to see if the problem is the phone or the pc.
I have a similar problem here at work. We all use Win7 PCs. Mine has the LGOG driver package installed and despite all efforts to install, etc my LGOG only charges. The notice window appears announcing that drivers are being installed, but then it fails.
When I go to my neighbor's pc, that doesn't have the driver package installed the notice window appears, says searching and installing drivers and I can see my phone in explorer. I can't explain but a different pc is a solution.
