After updating the firmware. I am unable to connect to wifi. The wifi will not even turn off. I cannot connect to my PC either. I have tried with other PCs as well and with different cables. All show same message "USB device not recognized. One of the devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message." I have updated drivers, disabled drivers, tried different ports, restarted device, restarted PC and still no luck. My device, GT-N8010 is running android 4.4.2 and not rooted. So now i cannot flash another rom or root my device to try and fix the problems. Any suggestions?

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...
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.

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.
I originally posted a threat up on reddit, but I couldn't find a fix for it.
I got a Note 2 do Android development on. I for the life of me cannot get the damn phone to connect to any PC I connect it to via USB; the phone charges, just does not connect. The USB icon does not appear on the device when connected either. I tried 3 different Windows machines, with the same warning I get that the device isn't recognized, but reads it as an 'Unrecognized Device'. I have also tried OS X, does not read it as well.
Here is some of the things I've tried from reading around XDA and other forums that haven't worked for me.
Solutions i've tried with no fix:
Various USB 2.0 cables (I do not have the original cable)
USB 2.0/3.0 and other ports repeatedly.
Enabling USB Debugging
Installing Kies, and Samsung driver from their site
Resetting battery
Booting into recovery mode with device connected
Dial codes for some reason do not work on my phone. I tried entering them with the stock dialer to bring the USB settings, but they don't work. I got around it by installing an app to get the USB mode to MTP, still does not work.
Rooting right now is not option, since Odin requires to be mounted to a machine in order to root. So I'm pretty much stuck. Still can't get this phone to sync on anything.
