SCSI, skener in Pingo 3.0

[Boštjan Jerko]

Pozdrav !

Na DEll-ov PC s Pingom 3.0 sem namestil Adaptecov SCSI kontroler 2940, 
na katerega imam priklopljen UMAX-ov skener Astra 1220S.

Ob "obuvanju" (boot) sistema se mi izpiše naslednje sporočilo:

scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36

sane-find-scanner mi ne najde skenerja.

Kakšne ideje kaj je narobe?
