My Lumia 640 LTE is no longer recognized over USB by any PC.
I rebooted the phone several times.
Tried different cables.
Three different PCs - one on W10 Anniversary, one W10 CU, one W7.
"USB device not recognized
The last device you connected to this computer malfunctioned, and Windows does not recognize it."
Other than shorter battery life everything else seems to work fine in CU.
Any help or ideas?
