Hi,

I try using my Epson USB Scanner with FreeBSD 5.3beta2, but it's only 
possible to communitcate with the scanner and sane one time then it 
hangs. The scanner is listed as supported (GT-7000 is the european model 
of the Perfection 636U).

bash-3.00# scanimage -L
device `epson:/dev/uscanner0' is a Epson GT-7000 flatbed scanner
bash-3.00# scanimage -L
^C
bash-3.00# scanimage -L
^C

These are the last lines of the debug output befor scanimage hangs:

Does anyone have a clue what happen to cause this?

Thanks in advance
