You should verify that the scanner module recognized your scanner. To do this, check if the output of "cat /proc/bus/usb/devices" lists your scanner with driver=usbscanner - if not (i.e. driver=none) you have to pass the vendor and product ID to the module. Either do modprobe scanner vendor=0x06bd product=0x2091 or specify options scanner vendor=0x06bd product=0x2091 in your /etc/modules.conf Also check that you have write permission on /dev/usb/scanner0.
