Oliver and Allan,

Thank you for the help. I have editted the snapscan.conf file so that the
path points to the firmware file. I tried again with the debugging level at

Andy-Whelans-Computer:~ andywhelan$ SANE_DEBUG_SNAPSCAN=255 scanimage -L
[sanei_debug] Setting debug level of snapscan to 255.
[snapscan] sane_snapscan_init
[snapscan] sane_snapscan_init: Snapscan backend version 1.4.53
[snapscan] add_usb_device(libusb:002:002-04b8-011f-ff-ff)
[snapscan] add_usb_device: Detected (kind of) an USB device
[snapscan] snapscani_usb_open(libusb:002:002-04b8-011f-ff-ff)
[snapscan] add_usb_device: error opening device
libusb:002:002-04b8-011f-ff-ff: Invalid argument
[snapscan] sane_snapscan_get_devices (0xbffff830, 0)

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
