my scanner disappeared after a driver update.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
printing works over Ethernet, scanning doesn't... i tried a PDF tool and another scanning program, both say no device. i'd love to understand how scnaner drivers relate to printer drivers, because i think that's where i'm getting lost, right now i'm photographing documents with my phone, which works, but it's not exactly professional... any help is welcome.
