hi, i have a hp 7400 scanner.

i have used it for several years on usb 1 but its just too slow for large
files, so i want to try scsi

to cut it short:

have tried 3 different scsi cards by 2 different manufacturers, adaptec and
tekram. and all have the same problem

it scans about 1/5 to 1/2 the page before halting. precisionscan pro 3.02
then locks for about 5 minutes.
it will scan small files say under 40Mb, but when it tries to do anything
larger it just halts before returning back to its 'home' position after
about 1 minute. I think it hangs where it waits for the scanners buffer to
empty before continuing to scan

i have tried:
changing scsi id, 2 through to 6
async and sync transfer modes
all transfer rates from 2 to 20Mb/sec
enabled and disabled every setting in the scsi bios in many different
combinations
updated every driver and bios
installed viewscan - interesting. this seems to work but transparency
scans are awful and it still hangs on the very large scans
tried scanner on another motherboard which had a different chipset

spec:
windows XP prof
hp precisionscan pro3.02
scanner bios 0.8s (but the scsi card reads it as 0.8a)
motherboard with vis kt600 chipset on sata raid 0 and pata raid 1

Please can somebody help. i think its the HP software. Im certainly never
going to buy another hp product again. its like my printer. a HP 1220c, hp
does not support it on xp in bi-directional mode, so i had to get a hp
jetdirect printer server to enable the full printing function. Their
hardware is good. its just the software. Seems like they produce these
things and don't give a damn if people have a problem with it.

Cheers, Mark
