[PLUG] Epson USB scanner trouble

[Sandhitsu R Das <sudas@seas.upenn.edu>]

I have Epson 636u USB - which is supported by the epson-sane backend in
sane.

I'm using Linux Mandrake 7.2 stock kernel 2.2.17-21mdk. This includes the
USB backport. The USB filesystem is mounted, all modules are loaded - but
the scanner is just not detected.

# lsmod

Relevant portion of /var/log/messages:

minor data

If anyone needs more info - I'll be happy to provide them.
