  The scanner has four buttons on the front, that is probably what it uses the
  interrupt for. Is there any Linux utility which supports these buttons?

  At least with kernel 2.2.16 with the backported USB drivers, the scanner times
  out when I attempt to do a scan.

  The command:

  scanimage -d hp:/dev/scanner0 -v

  Does nothing for a few minutes, then I get this message in the messages log:

  Jul 13 21:28:01 alfred kernel: usb_control/bulk_msg: timeout
  Jul 13 21:28:01 alfred kernel: scanner.c: write_scanner: NAK recieved.
  Jul 13 21:29:14 alfred kernel: usb_control/bulk_msg: timeout
  Jul 13 21:29:14 alfred kernel: scanner.c: write_scanner: NAK recieved.

  --- Contents of: /etc/sane.d/hp.conf
  /dev/scanner0
  option connect-device

      ---
      /dev/scanner0 was created with "mknod /dev/scanner0 c 180 48"
      Also, I loaded the scanner.o module with:
      /sbin/insmod /lib/modules/2.2.16/usb/scanner.o vendor=0x03f0 product=0x0701
      -----
      The problem may be the backported USB drivers, I am going to try kernel
      2.4.0-test3 as soon as I get it installed, and see if it works then.
      Sincerely,
      Terence Haddock
