Dear member of SanDisk Community, welcome.
[ Can there be too many USB drivers installed? If so, is there any way to “clean out” these USB drivers so that a “new install” can be completed?
I realize these don’t actually install drivers, but they install something. ]
1- See if it helps this tool, for general cleaning (portable app, free): Link Removed
2- Maybe what happens, is that there a corrupt line in the registry/USB_,_ that detects an UFD as “problematic”.
Then, try with the tool (portable app, free): Link Removed
3- Also, the intensive use of USB ports, generates “USB junk” in the registry.
Then, to clean easier the “USB junk”, you can use the tool (wXP, Vista, w7), (portable app, free): Link Removed
Luck, and then you tell us, what happened, please.
Regards, Alfred. (Google translated)
