linux-l: /proc/sys/kernel/sg-big-buff ???

[Carsten Wartmann]

Hi, 

ich versuche gerade einen Scanner mit SANE 0.73 zum laufen zu
bekommen, das produziert mir strace:

mero:[sane-0.73-dist] #scanimage -d microtek:/dev/sgd
scanimage: open of device microtek:/dev/sgd failed: Invalid argument
mero:[sane-0.73-dist] #

Das "microtek:" wählt den backend aus.

Das /proc/sys/kernel/sg-big-buff gibt es bei mir anscheinend
nicht. Kann das das Problem sein. Was ist das überhaupt? generic-scsi
gibts als Modul und wird auch automatisch geladen.
