Done that, and tail shows it being allocated IRQ 10.  It's correctly named, so 
I believe that it is the correct driver.

Again, all documentation I can find refers to tmscsim as the correct driver.

sg and scsi_mod are now both loaded (no entries into messages when I 
modprobed, so perhaps it already was loaded).  scsi_mod is listed as being 
used by sg, tmscsim and sd_mod

I believe that is true - I didn't recognise the name of this driver.  However, 
this driver was written by a Tekram engineer, so it would seem reasonable 
that it replaced an older one.

Yes and no.  It sounds as though it should help, but I feel to be up against a 
blank wall.  The first recommendation for tracing missing devices is to type 
'cat /proc/scsi/scsi', which returns no devices.  Next, they suggest 
'cat /proc/scsi/tmscsim/H' where H represents the adapter device numer, 
usually 0.  There is no /proc/scsi/tmscsim.  

Reading http://www.garloff.de/kurt/linux/dc390/README.tmscsim made me aware 
that there is more than one version of DC390, but I checked the card's bios 
configuration utility, which tells me that it is the basic DC390, using the 
SCSI chip AM53C974A, which ties in with the info I got from tailing messages.

Next I tried 'echo "scsi add-single-device 0 0 3 0"' which gave me 'No such 
file or directory' - the file exists, but is 0B long.  I gave the parameters 
from my dim memory, so I could be wrong about them.  The SCSI card BIOS 
reports Bus~ 00h, Device# 00h, Function# 00h, IO Address EC00h.  Most of the 
settings in there appear to be for SCSI drives.  ISTC that nothing in there 
had to be changed for using it with the scanner.

I am still worried that all the drivers I can find date back to 2000 at the 
latest.  Maybe they are too old, but then I think this driver was included in 
the distro.  I'll keep reading, but I'm very confused.
