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...
Whenever I plug in my phone to install the drivers so that my phone will be recognized by windows 7 x64, MTP drivers fail to install. If I start Kies, and try to connect it says "Devicemanager.exe has stopped working" and then my SGSII is just stalled in kies as "Connecting".
Any idea how to fix this???
...
I have now tried uninstalling kies and galaxy s2 drivers, reinstalling kies, downloading drivers from within kies, and then connecting the S2 via usb. The second sgsii gets recognized, same message "Devicemanager.exe has stopped working" and the kies "connecting..." loop.
...
No one can help? I want to unlock my SGS2 so I can use it, but I can't unlock it unless I root it, and I can't root it unless kies is working. Kies refuses to work.
...
Send halp soon!
Either Update your Windows and try again or try to connect in Safe Mode and see what happens.
...
I booted into safe mode, plugged it in while running kies. No more error, but still doesn't recognize. Booted back into regular mode, error returns, still no recognition
windows is up to date.
...
Things I have also tried:
reformatting the internal memory.
uninstalling/reinstalling drivers from phone
uninstalling/reinstalling drivers from kies
uninstalling/reinstalling drivers from phone w/ usb debugging on
transfering devicemanager.exe from another computer over my current kies installation.
I am totally stumped...

Try to re-install the Phone drivers (uninstall it first from Control Panel) and try to connect, in Safe Mode.
STOP using Kies and install a custom rom! I never ever installed Kies and my phone is completely up to date.
Use a different pc if you're so desperate. It seems your pc just doesn't like your phone.
Use kies air instead or use your phone as a mass storage device and don't waste your valuable time trying to fix that buggy, heavy and, in my opinion, useless software installed on your computer known as kies.
I had the same problem. I uninstalled Kies then disabled my firewall (Comodo) and reinstalled. Now it works fine.
Okay, I reinstalled Windows about a week ago. All my stuff is erased, of course. I could connect to PC Companion with no errors, but now that I reinstalled it, at first, it executed Camera and Scanner Wizard. So I disabled it. Now, it won't load Phone Mode, but it loads Mass transfer and Phone Mode when debugging is on.
So what should I do? I already tried reinstalling PC Companion.
I just plugged my S3 into my PC to copy some files over, and all of a sudden i got this error from windows saying USB Device not recognized and this USB device has malfunctioned. I heard its a known problem on android phones, but never really found a solution for it. Can someone help?

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.
