tlug: Device drive resource

[YAMAGATA Hiroo <hiyori13@example.com>]

Hi, I got this mail from an Ukranian guy that I gave some Linux CDs. I
don't quite understand his description of his problem, but if any of you
guys do know some resources concerning device drivers, could you let him
know? Thanks.
