With Windows 8.1, KB3022345 is causing “USB device not recognized” error messages on the desktop whenever you plug in a USB device, such as a phone or a flash drive, such as a phone or a flash drive.... Removing the update doesn’t solve the problem, so for the moment, the only way to fix it is a system restore that could get the computer to a previous state, when the update is not installed.
[ Everything seems to be working fine in Windows 7.]
