  Cool, thanks, that fixes the floating point bug... but it's still not
  working properly.

  Now when I test the backend, scanimage goes into an infinite loop
  and I am left with no choice but to hit Ctrl-C.

  The debug output of "scanimage -T" (which I put up at
  http://www.tygger.net/~wico/snapscan/debug1.txt ) has a scary
  looking line near the end that says:

  [snapscan] (undef): Hung up because expected bytes is 0. Please report!

  ...so I figure I'd better do as it says :)

  Anyway, I'll stock up on chocolate, Coca-Cola and cigarettes and see
  what I can do tonight - but I'm a bit of a newbie when it comes to the
  mysterious world of SCSI so I doubt I'll be able to come up with much.

  Ben.
