Highscreen HighScan and microtek2-backend

Hi!

Got a Highscreen HighScan yesterday and after some struggling I got it
working with the microtek2 backend.

Perhaps this information is usefull for some people ...

I first tried to get the scanner running with the microtek backend as the
manpage said it supports it. But even fooling the backend concerning the
reported model-code, it won't run.

So I tried to use the microtek2 backend and after makeing it accepting the
modelcode "0x92", which is reported by the scanner, it worked.

I am using the Adaptec AVA1502AE SCSI-Adapter that came with the unit. At
first, I disabled "SCSI-DISCONNECTION" as it is said in the
scanner-manual. But using this setting, it took quite a while until the
scanner actually started scanning, and lot's of interrupts were produced
on the aha152x-driver. After enabling SCSI-Disconnection on the Adapter,
everything worked fine.

I guess, the HighScan is nowadays a Microtek 330.

If some further information is needed to integrate support for this
scanner into the backend, please let me know.

But there's one thing I don't understand:
Although using a separate SCSI-Adapter for the Scanner, it locks the whole
system while the scan is in progress.
I can't even move the mouse while doing a scan.
What's the reason for this???

Greetings,
cu Florian
