[sane-devel] Prisa 620S just clicking

[Steffen Kluge]

Hi,
I'm using a Prisa 620ST. It works quite well, though not perfect yet.
I had a lot of trouble in the beginning, most of which I attribute
to SCSI controller and sg driver.

Early versions of the sg didn't work well with any buffer size setting.
As of version 3.something the problems mostly went away. 

The SCSI controller bundled with the scanner (Acard) didn't work at
all, though it works in Windows. An Adaptec AHA1542B I tried didn't
work reliably. The AHA2940 works alright with both versions of the
aic7xxx driver, but I still get I/O timeouts every once in a while.

On a whole, the 620ST/AHA2940 combo is very useable (and useful) with
sane (version 1.0.4).

Cheers
Steffen.
