Unhappy xsane does not detect HP Scanjet G3110

Hi,

I have an HP Scanjet G3110 and I am trying to use it in a Fedora 10 box. Unfortunately xsane can not detect the scanner.

I get the error message:
Failed to open device 'v4l: /dev/video0': Invalid argument.

lsusb returns:
Bus 001 Device 007: ID 03f0:4305 Hewlett-Packard
Bus 001 Device 004: ID 046d:09a1 Logitech, Inc. QuickCam Communicate MP/S5500
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

The only HP usb device attached is the scanner. To mention also that the site of the sane project states a basic support for this scanner.

I would very much appreciate any help to fix this problem.

Thanks in advance,
John

Where does it state that this scanner is supported? I don't see it listed here http://www.sane-project.org/sane-mfg...EWLETT-PACKARD

It's certainly not supported by hplip.

In this page, http://www.sane-project.org/lists/sa...EWLETT-PACKARD, it is stated that a basic status.

[ScanJet G3110 USB 0x03f0/0x4305 Basic Similar to hp scanjet 4370 hp3900
(0.12) sane-hp390]

Nevertheless, I found a solution. I installed the backend hp3900-series 0.12 updated, the stand-alone application, then I edited the /etc/sane.d/hp3900.conf by adding the entry:
# HP Scanjet G3110
usb 0x03f0 0x4305

and disabling the:
# HP Scanjet G3010
#usb 0x03f0 0x4205

xsane recognizes the device as RTS8822 chipset flatbed scanner. It works now.

The output of 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=0x4305 [hp scanjet], chip=RTS8822) at libusb:001:003
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.

Good going. And good that you posted your solution which always helps out a bunch of other people, even though that tends to go unnoticed.

How did you find out that the backends were similar?

In your post, you said that you found a similar back-end for your scanner. You then substituted that product code for the other code. I have a Epson, and my product code is 0X0838a. This code is the same for 2 different scanners. The closes other code is 0X0838 and it didn't work. The next one is 0X0839 for another scanner and it didn't work. So, how did you find out that the product code was similar to substitute?

I noticed that you have an Epson scanner do you have search whether this back-end supports Epson scanners?

In my case the two HP scanners had different codes.

# HP Scanjet G3110
usb 0x03f0 0x4305

# HP Scanjet G3010
#usb 0x03f0 0x4205

The code for G3010 was already in the hp3900.conf after the installation of backend hp3900-series 0.12 and I disabled it.

For your scanner have you install libsane-hpaio?
Code:
yum install libsane-hpaio

Yes, I just checked and libsane-hpaio is installed. I check with sane, and their web site says that all operation may not work. It shows up, but won"t turn on. Start: operation not supported. Been that way for over a year. May have to change out of Fedora to get it to work.
