How to test an unsupported scanner (CanoScan LiDe 90)?

[Peter Ulrich Kruppa]

Hello list,

I have purchased a scanner yet unsupported by sane
(CanoScan LiDe 90). It is at least detected by

   # sane-find-scanner -q
   found USB scanner (vendor=0x04a9 [Canon], product=0x1900
   [CanoScan], chip=GL842) at libusb:/dev/usb1:/dev/ugen0

- No /dev/uscanner0 is produced.
-  # scanimage -L
   says no scanners were identified.

I would like to test if it might work with sane-genesys
backend.
How can I do this?
I am running FreeBSD 7.1-PRERELEASE amd64 .



Thanks for your answers, comments, help, etc..

Greetings,

Uli.
