No surprise here. IMHO, those cards are worthless pieces of junk.

Good!

Can you tell me exactly what leads to hangs? I won't claim that the
Mustek backend can avoid hangs for all possible error cases, but I
have been using the backend for quite a while now and don't even
recall the last time it got stuck (and I'm not particularly careful in
dealing with the scanner).

This looks like the read was hit by the SCSI timeout (see comment in
sane-mustek(5)). If you get "ncr dead?" messages in your /var/log/messages
file, than that's the problem. In the file:
/usr/src/sys/linux/drivers/scsi/ncr53c8xx.c
you should find a line:
if (np->latetime>10) {
right above the "ncr dead?" message. Change the 10 to, say, 60
(seconds) and the problem will go away.

Yes, based on the info you provided, it looks like it's really just a
regular Paragon 600 IISP with newer firmware. That's good.
