[sane-devel] HP Scanjet 4100c USB on FC5

[Sean Laurent]

Hi,
I'm attempting to get an HP Scanjet 4100c USB scanner working on
Fedora Core 5 with a 2.6.16 kernel, but I seem be having some
difficulties. When I connect the device, I see the following messages
in /var/log/messages:

---snip---
kernel: ohci_hcd 0000:00:02.0: wakeup
kernel: usb 1-3: new full speed USB device using ohci_hcd and address 4
kernel: usb 1-3: configuration #1 chosen from 1 choice
---snip---

I then tried running sane-find-scanner and scanimage as root.  When I
run sane-find-scanner, it sees the scanner:

---snip---
$ sane-find-scanner
  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0101 [HP
ScanJet 4100C]) at libusb:001:004
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.
---snip---

However, when I try to use scanimage, I run into problems:

---snip---
$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

$ canimage -d hp:libusb:001:004 --format tiff > ~/temp.tiff
scanimage: open of device hp:libusb:001:004 failed: Error during device I/O
---snip---

At this point, I'm stumped.  Any suggestions would be greatly appreciated!
