  Hi there,

  Has anyone get the Scanner Acer S2W 3300U working ?

  I'm using a 2.4.0 kernel.
  I can modprobe the "uhci.o" followed by a modprobe scanner and get the
  messages that are below.

  When I modprobe that module, the scanner "blinks" but that all.

  Is this scanner supported ?
  Is it compatible with another model that is supported ?
  Where can I get more information about how to get it working under Linux ?
  What is the "SANE scanner backends" that I should use to get it working (if
  any)?

  Sorry for so many questions but, any info is greatly appreciated.

  Thank's in Advance,
  Nuno Nunes
