[LUGOS] SCSI, skener in Pingo 3.0

[Iztok Kham]

LP!

Sicer za linux konkretno ne vem, vem pa, da imajo tile skenerji težave z 
UW kontrolerji.
Ko sem zase iskal rešitev pred kakimi 4, 5 leti, so na UMAXovi strani 
govorili, da je potrebno imeti nek "High-byte" adapter, ker sicer ne 
znajo delovati...

Se pravi, da bi v tem primeru bil bolj problem v strojni in ne 
programski opremi.

P.S. Sam sem takrat stvar rešil kar z enim najbolj osnovnim IWILL 
kontrolerjem.
