Hey that's cool! They even put this Linux panel driver on the CD. As
far as I know that's the first time Mustek did that.

Thanks. I didn't realize that the ps1fw.usb file is also in the RPM. I
just saw the ps2fw.usb which didn't work on my scanner. The ps1fw.usb
does, however. So everyone can get it from their website (at least for
Bearpaw 1200 CU scanners).
