Newbie Q: Accessing Scanport SQ4800 via SANE

Hi,
I have a Scanport SQ4800. According to the manufacturer,
this is a private labelled version of the Microtek
Scanmaker E3. Works fine in Windows with the crappy SCSI
card that came with it.

To use it with Red Hat Linux 6, I installed an Initio 9100a,
added the right modprobe line to /etc/rc.d/rc.sysinit, and
now /proc/scsi/scsi says
Attached devices:
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: N-TEK Model: NuScan II Rev: 1.60
Type: Scanner ANSI SCSI revision: 03

Now, I have no idea how SCSI works on Linux, but I gather than
one of /dev/sga ... /dev/sgh will correspond to the scanner.
Don't know which one.

I saw a utility 'scsi_info' that will open both a given
/dev/sg? entry and /proc/scsi, and output info about what
SCSI ID the device corresponds to. I ran that as root on each of
the /dev/sg? entries, and got
open() failed: Permission denied
on /dev/sga, even after chmod 644 /dev/sga, and
open() failed: Device not configured
on the others. This doesn't seem right.

I also tried making /dev/scanner be a symbolic link to
/dev/sgg, creating a group 'scanner', setting it to group 'scanner',
and setting it group writable (as hinted at in the SANE docs)
and tried 'scanimage', but no joy; no SANE devices were found.

Heeelllppp...
Thanks,
Dan
