You might want to look for an email I sent out a while back on snapscan and USB gotchas.
Here are a few things about that again. If I ever get some free time, I'll clean up the USB code so its not such a problem.
1) Do not have a /dev/scanner link if your using USB. It just confuses to much of the current code.
2) Make a symbolic link from /dev/usb/scanner0 to /dev/usbscanner (if your scanner is really at scanner0).
3) Make sure you have modified your snapscan.conf file and have /dev/usbscanner listed in it.
4) Do not run *scanimage from the backend directory (it will use the wrong snapscan.conf file).
5) run scanimage with -d snapscan:/dev/usbscanner
Part of the problem is that the device name /dev/usbscanner is hardcoded in parts of the scapscan USB driver. If thats not consistently used then you will see the "... not in current list" error.
