  Hi,

  I have a S20, but no other USB scanner - I can't tell whether I
  set things up correctly. Here's what I did:

  modprobe usbcore
  modprobe usb-uhci
  insmod /lib/modules/current/misc/scanner.o vender=0x03f0 product=0x0102
  mount -t usbdevfs none /proc/bus/usb

  hp.conf says:
  /dev/usb/usbscanner0
  option connect-device

  the device file:
  crw-rw-rw- 1 root root 180, 48 Mar 17 19:47 /dev/usb/usbscanner0

  When I now try to start xsane or xscanimage, it will hang for
  about a minute, eating all available CPU time. The syslog says:

  swamp kernel: usb_control/bulk_msg: timeout
  swamp kernel: scanner.c: read_scanner(0): NAK received

  When I unload the scanner module, xsane works as usual again
  (I also have a UMAX SCSI scanner)

  Regards,
  Peter
