By an astoundingly strange coincidence, my LiDE 20 wasn't recognised by
sid about two hours ago.
Unfortunately, the simple answer, as revealed by /var/log/syslog, was
that my USB hub didn't have enough current to drive the scanner. I
plugged it into one of the tower USB ports, and it buzzed and lit up
and ran happily.
It would be nice if it was that easy for you. If it isn't, I can drag
it back downstairs (it's usually attached to the wife's Win7 machine)
and try to work out what it needs. A glance at lsmod shows me nothing
that I can associate with scanning, but there's quite a lot there I
can't identify at all. The syslog file doesn't mention anything being
loaded.
