how to make SCSI work?

[Miernik <miernik@ffii.org>]

I am trying to use a PCI SCSI controller to which I have connected an
UMAX Astra 600S scanner.  I can't get the system to see it, and I am
somehow stuck.

First of all some information about it:

I use Debian GNU/Linux sid, kernel is standard Debian kernel from deb
package. 

||/ Name                           Version      Description

localhost:~#

lspci -v shows:

0000:00:0a.0 SCSI storage controller: Adaptec AHA-2940/2940W / AIC-7871
        Flags: bus master, medium devsel, latency 32, IRQ 10
        I/O ports at d000 [disabled] [size=256]
        Memory at e5800000 (32-bit, non-prefetchable) [size=4K]

in dmesg I see things like:
...

The scanner is configured as device 6 (with a mechanical switch on it).

How am I suposed to make this work?
