Did you say what kernel you were using? I have a similar problem with my
BT958... I'm thinking this is likely a sg driver issue though. Anyways,
I'm going to overhaul my hardware... I have an odd motherboard and am
using software raid. I'm grabbing a AMI MegaRAID controller, replacing
the motherboard, and then I'll see how the BT958 fairs with a stock
RedHat 6.0 kernel. If it turns out to be the BusLogic controller I'll
have to see about swapping SCSI cards for the scanner... I think that
cheap AHA-1505 that came with the scanner works with the aha152x driver.

Right now this problem is greatly hindering my ability to do SANE
related development.
