Ah. So it is needed with ppscsi for generic support? I am running a
BusLogic SCSI controller with a CDROM, CDRW, and SyJet. (I picked up the
parallel port scanner cheap and don't use it enough to justify actually
getting a SCSI scanner.)
I actually got the scanner to work by simply insmod-ing, sg, ppscsi, and
onspec modules manually without removing any printer mods.
My original module list looks like: (printer functional)
/sbin/lsmod
Module Size Used by
sound 58424 0 (autoclean) (unused)
soundcore 2404 3 (autoclean) [sound]
soundlow 300 0 (autoclean) [sound]
tulip 24740 1 (autoclean)
nls_iso8859-1 2020 3 (autoclean)
nls_cp437 3548 3 (autoclean)
vfat 9084 3 (autoclean)
fat 30208 3 (autoclean) [vfat]
BusLogic 87620 1
After loading the other modules: (scanner functional, lp locked)
/sbin/lsmod
Module Size Used by
parport_probe 2980 0 (autoclean) (unused)
lp 5052 0 (autoclean) (unused)
parport 7060 0 (autoclean) [parport_probe lp]
onscsi 14348 0 (unused)
ppscsi 10128 1 [onscsi]
sound 58424 0 (autoclean) (unused)
soundcore 2404 3 (autoclean) [sound]
soundlow 300 0 (autoclean) [sound]
tulip 24740 1 (autoclean)
nls_iso8859-1 2020 3 (autoclean)

vfat 9084 3 (autoclean)
fat 30208 3 (autoclean) [vfat]
BusLogic 87620 1
I thought that I loaded sg myself last time, but this time, I needed to
rmmod it before the scanner worked. It seems to autoload, so the problem
was probably that I loaded it manually.
/sbin/lsmod

I can still mount and unmount the BusLogic devices and the BusLogic mod
goes into the list when I do so. Oh well, as long as they work. ;)

Both are on at boot for me.

The file is in the same place with RH.

I'm using:
kernel 2.2.12
ppscsi and onscsi modules (2.2.13-ppSCSI-19990712)
Microtek V310 using the OnSpec 90c26 chip
sane 1.0.1 (from rpm)
Microtek2 backend ver 0.6
HP Laserjet 5P printer
Issuing rmmod to onscsi, ppscsi, and sg doesn't restore the printer.
I've not had the trouble that Marcel Pol reported in not being able to
load the modules at the same time. I've not tried using modprobe
(suggested by Michael Eyrich), yet. I may get a chance to try doing so
next week. I'll let everyone know the results. I have not changed the
default Linux /etc/conf.modules beyond adding "alias parport_lowlevel
parport_pc" in order to get the printer to work shortly after my upgrade.
Jason, I'm also running the 2.2.12-20 kernel. As I said above, I've
gotten ppscsi and onscsi to work by using the 2.2.13-ppSCSI-19990712
patch.
