Failed to open device gt68xxLlibusb 004:002 invalid arguments error message


Need help regarding installing a usb scanner in Fedora Core 3 Linux. My sane-backend version is 1.0.14 and the libusb is 0.1.8-3. When I enter the command sane-find-scanner, it detected my genius colorpage vivid 4x that have a value of gt68xx:libusb 004:002.

When I tried to scan an image using GIMP, the xsane front-end software issued an error message of "FAILED TO OPEN DEVICE GT68xx:libusb 004:002 invalid arguments".

What am I going to do? I have done all the means to have the genius scanner work on Fedora Linux core 3.

edit the gimp rc files to choose the correct device

I am using Fedora Core 4 and having a similar problem with gimp-2.2.7-4.
The command "scanimage" succeeds but gimp fails. After using strace
to see what scanimage was doing, I noticed that gimp was trying to
access a different usb device. Gimp used epson:libusb:001:005 whereas
sane-find-scanner finds it at libusb:001:007, so I greped ~/.gimp-2.2
for 005 and found it in files "menurc" and "pluginrc". I edited those
while gimp was not running, and the next time I ran gimp worked like a
charm. Obviously this is a work around and not a fix.

If this is not your problem, try becomming root and changing the
permissions of your usb devices. "chmod a+rw /proc/bus/usb"
