  Thanks for the comments so far. It does sound like I will not be
  overlapping with other peoples work very much.

  A minor clarification on what I'm also planning on doing. I did
  mention that it would probably have compile problems currently on
  other platforms. This is probably not true since no one uses any
  USB specific ioctl() calls that could fail. Right now its all
  read()/write()'s. In that regard I was thinking more along the lines
  of future USB drivers that could kill compiles if they accessed
  ioctl()'s.

  Also, at least on Linux most of the usb work is done by scanner.o.
  Therefore I'd like to make a generic wrapper in case other platforms
  don't do as much work. Also, I'm thinking of moving the current USB
  code from the snapscan driver that simulates sanei_scsi_cmd()
  function calls and turns them into USB calls. Since current USB
  devices are usually SCSI over USB it should be handy (can be shared
  between the epson and snapscan today even).

  This part is lower on my feature wishlist. I'll be working on the
  config files and a way to make SCSI and USB scanners coexist happily
  at first.
