It happens to me too that i get i/o errors.
Strange thing is it happens even more with Sane 1.0.2 then with Sane 1.0.1.
The firmware could make a difference, you should at least use Firmware 1.60 is
what i've heard. There was just a mailing about that this week. My scanner has
firmware 2.1 but it still happens, but well, maybe less then with older
versions of the firmware.
i tried my scanner with the cheap adaptec isa card, and it didn't seem to make
much difference, so a cheap scsi card might not be the solution. I don't know
if an expensive scsi card would make a difference.
For me it is functional, allthough some scans i have to do over again. And with
an i/o error i have to turn the scanner off/on. Sometimes even rmmod and insmod
the onscsi module.
I hope it will become functional for you too.
