[sane-devel] Redhat 9 mustek 1200 xsane invalid argument

[Martin]

Hello,
I can get my mustek 1200 scanner working using,

As a normal user I can scan it:
$ /usr/local/bin/scanimage --device-name=gt68xx:/dev/usb/scanner0 --mode 
Color --resolution 600 > aaa.pnm

I can open up the file in Gimp and save it as aaa.jpg file format:
$ gimp aaa.pnm

But...
when trying to execute the xsane command,

$ xsane gt68xx:/dev/usb/scanner0
or
$ xsane

I get error message, >> Failed to open device gt68xx:/dev/usb/scanner0: 
Invalid argument.

Any ideas would be greatly appreciated, thanks.
