I meant residual lengths on reads... Peter corrected me. Apparently some scanners don't care. Of the supported cards, the only ones I know of that do the residual reads correctly (which is a prerequisite for attach/detach in target mode, I think, and the source of my confusion) is the Adaptec 1542B. The 1542A and 1542C won't work. I don't know about our other drivers. See the "SCSI IP" thread regarding my request for "user interrogation of capability bits". Probably, each driver and capability sets ought to be doc'ed on each release.
