  I don't think so. The API remains compatible for all 1.x versions and
  I don't think there were SANE-internal changes that require changes in
  the backend. However some bugs were found which may be in other
  backend, too (see TODO file).

  At least until now nobody has written such a file. At least concerning
  the Linux scanner module I don't see any advantages in this (just
  simple reads) but if there are any, please tell me. I don't know if
  this may be interesting concerning libusb or other operating systems.

  Bye,
  Henning
