[sane-devel] Unstable scanning with Fujitsu fi-7160

[Simon Matter]

Hi,

I try to use a Fujitsu fi-7160 scanner on AlmaLinux 10 (RHEL10 compatible).

The scanner works some times but then fails and scanimage reports
"scanimage: open of device fujitsu:fi-7260:1433 failed: Invalid argument".

The scanimage command is always the same and it can work 5 times and fail
on the next.

The problem happens when connected via USB2 port or USB3. Different other
Fujitsu fi-xxxx scanners behave exactly the same.

When the scanner fails it is also not detected via "scanimage -L".
Powering off and on the scanner brings it back to life.

Any help on this issue would be much appreciated.

Thanks,
Simon
