Please also have a look at the mailing list archive. Similar problems have been discussed quite a few times during the last weeks.

Sub=00 Prot=ff Driver=(none) That's the interesting line. Your scanner was not detected by the kernel scanner driver: Driver=(none). Try: rmmod scanner; modprobe scanner vendor=0x04a9 product=0x220d The line should now have: Driver=usbscanner. > I AM USING THE FOLLOWING CONF FILE > plustek.conf with the following settings....

Do you really have 3 scanners? Usually it's /dev/usb/scanner0. If you want to try the libusb device mentioned above, that would be: "device libusb:001:002", but I'm not sure if this works. Better use "device /dev/usb/scanner0" if that's printed by sane-find-scanner. [...] > # > # and of course the device-name > # > device /dev/usbscanner2 Why do you use the device option twice? Just use the last one (with the correct device file) and remove the first one. > NOW, what am i doing wrong? > i have gone through many readme and install files. Too many, probably :-) The fastest way to run USB devices supported by the plustek backend usually is: rmmod scanner; modprobe scanner vendor=... product=... edit plustek.conf, change /dev/usbscanner to /dev/usb/scanner0 (or whatever sane-find-scanner prints) Bye, Henning
