I have the vendor info as options in my modules.conf, since it is an
Epson using the Plustek driver.

I had the same problems before I upgraded. Anyway, my /dev/usb/scanner0
file is created on the fly when the scanner is plugged in, and the
permissions seem to be assigned dynamically: the owner is the user
logged in under X...
As I said below, everything seems to be set up correctly driver-wise,
since I can scan perfectly using VueScan (commercial software, but cheap
and mighty interesting). It's just Sane that seems to react strange with
this "device already open" message.
