Trying to use a HP 6300 scanner with SANE. Particulars:
Ubuntu 10.10, kernel 2.6.35-28-generic-pae
Scanner connected through usb
Results of 'sane-find-scanner':
found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0601 [HP
ScanJet 6300C]) at libusb:005:002
here is /dev/bus/usb/005 directory:
crw-rw-r-- 1 root root 189, 512 2011-05-13 20:22 001
crw-rw-r--+ 1 root scanner 189, 513 2011-05-13 20:51 002
device 001 is the root hub.
symlink to scanner is present in /dev:

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).
[hp] sane_exit called

I see the 'invalid argument' but I don't know what it is complaining about.
Are the major/minor numbers for /dev/bus/usb/005/002 OK? Everything
I've read says major 180 for scanners.
What am I missing?
