Suddenly my Note II will not connect to my PC. The message on the PC side is USB Device not Recognized. The message is consistent whether the phone is in Installer Mode, MTP mode, or PTP mode. I have tried it on three different PCs (one Windows 8.1, two Win 7) with four different cables and the result is the same. I have powered down and up and the result is the same. Don't know what to try next.
Let's try to save your phone and bring it back to life! Together we will dig deeper to see what's going on. Does the charger recongize phone when it's plugged into wall?

USB Debugging feature is OFF. I had turned it on a few days ago and tried plugging the USB cable into my computer. I didn’t know what to look for, and I didn’t see anything happen on the phone side. Then I turned it off because it said it was a security risk.
I just plugged it in again to make sure I copied the exact error message, and it connected successfully in MTP mode. Then I switched to PTP mode, and it still worked.
I guess for the moment my issue is solved and the question is closed.
Thanks for trying.
