  Hi Tim,

  please try two things:

  1.: Use hp.conf with only one line

  /dev/scanner

  2.: Use

  export SANE_DEBUG_HP=128

  and run

  (x)scanimage hp > hp.lis 2>&1

  to get mor information where the backend might crash.

  What version of the USB module are you using ? The support for HP4200C
  is pretty new.
  Please check with http://www.jump.net/~dnelson/linux/usb.
