[Linux-parport] ppscsi: epst with kernel 2.6.10

[J Fairbairn]

I've been using an HP scanner (HP5100C) on a parallel port
with kernels up to 2.4.22 with the ppscsi+epst patch, but
I'm considering switching to a 2.6 kernel.

I've trawled this list for messages relating to this; I
found the patch for 2.6 kernels (from
http://penguin-breeder.org/kernel/download/linux-ppscsi-2.6.x.patch.gz)
and applied the later patch (from
http://lists.infradead.org/pipermail/linux-parport/2005-January/000216.html)
to make it compile with 2.6.10 (parport_get_port needed
exporting -- the patch needed tweaking to make it apply),
but I couldn't find anything that takes it further, so I'm
hoping for some help.

What I have now is a 2.6.10 kernel with parport_pc, sg,
ppscsi and epst all as modules (scsi_mod is built in as some
of the hard discs are scsi).

When I modprobe epst, the module loads happily, but scsi
doesn't report the device -- epst logs it, but it just
doesn't seem to get attached to /dev/sg[anything]. What do I
try now?

I've attached logging messages and the contents of
/proc/scsi/epst/3. /proc/scsi/scsi just lists my hard disc
and CDROM, not the scanner. As can be seen from the log, 
epst is talking to the scanner and discovers its device 
string, but scsi just says scsi3: epst.  

Aside: the first time I loaded the modules it came out 
as scsi2, and unloading produced a complaint about epst not 
releasing the driver.
