I take it your are using the devfs system then? I hadn't braved
that bit of rather choppy water since it couldn't find the hard
drive after mounting it during the bootup. Made for an interesting
recovery as I had to drop back about 3 kernel versions on the grub
screen before it would reboot.
I've done that (reboot) too since I last emailed about this, and on
the reboot, when I checked the perms on /dev/usb/scanner* it still
came back as crw------, but with gene:root as owner:group, whereas
whe n I looked yesterday I could have sworn it said root:root
straight across the board for all 16 devices. Snilmerg?
In any event, I'm fresh out of ideas with those 2 questions, anybody
else have any ideas here?
