Hi! Seems that the CanoScan LiDe 90 is one of the scanners built by Canon that are not supported well. That's a reason to avoid them. :-) I had similar issues with a LiDE 45 (I think it was), and I did soon replace it with a SCSI scanner that worked out of the box without problems.

Mayve the SANE team will get this scanner to work later on. But at this point in time, the scanner will be outdated. :-) > In the meantime I have played around a little bit: > I put vendor and product id's into > /usr/src/sys/dev/usb/uscanner.c and usbdevs and rebuilt > my kernel. > So now I get > # dmesg | grep uscanner > uscanner0: <Canon CanoScan, class 255/255, rev 2.00/3.07, > addr 2> on uhub1 > which changes: > # sane-find-scanner -q > found USB scanner (vendor=0x04a9, product=0x1900) at > /dev/uscanner0 > Also I tried an appropriate entry in > /usr/local/etc/sane/genesys.conf > but the result of > # scanimage -L > remains the same (not identified) and > # scanimage -d genesys:/dev/uscanner0 > image.pnm > scanimage: open of device genesys:/dev/uscanner0 failed: > Invalid argument This indicates that this scanner works differently than those usually supported by the genesys backend. I "love" Canon for making things complicated exactly this way. Maybe this scanner is compatible to another driver, but that's only a guess. Maybe it's not compatible to anything that exists. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
