OK, I ran the two commands again as root and 'sane-find-scanner' yielded some interesting info but scanimage did not. See the typescript I included below. Script started on Thu 22 Sep 2011 05:48:19 PM PDT root at linlap ~# scanimage -L 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). root at linlap ~# sane-find-scanner # sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. # No SCSI scanners found. If you expected something different, make sure that # you have loaded a kernel SCSI driver for your SCSI adapter. found USB scanner (vendor=0x04b8 [EPSON], product=0x013a [EPSON Scanner]) at libusb:001:002 # Your USB scanner was (probably) detected.
