[sane-devel] fujitsu FI-5220C Flatbed scan hangs after a few scans

[Markus Haberkorn]

Hello,

I'am using a Fujitsu FI-5220C scanner with backend
version 1.0.19. The scanner works fine with the adf unit.
But I have problems to scan several sheets with the faltbed unit.
A few times it works without any problem. But with no reason for me 
an error occurs and no side is scanned anymore, until i unplug and 
replug the USB connector. Afterward the flatbed unit works fine for 
a few sheets.

Details
- Fujitsu FI-5220C
- backend fujitsu version 1.0.19 as backport
- debian etch
