[PARPORT] Shuttle EPST driver...

Sat, 18 Dec 1999 22:25:19 -0800


I have been trying to get this ppSCSI patch to work for a week or so
now, and I am (with the help of people on this list) getting much
closer. Unfortunetly, I am not close enough yet. Here's where I'm at
and what I've done:

(1) I patched my 2.2.13 kernel with ppSCSI-0.91.patch and rebuilt my
modularized kernel. This is all on a Redhat 6.1 system. Worked great
(after a couple of initial snags).

(2) Rebooted, and attempted to modprobe the modules I need for my
parallel port HP ScanJet 5100c to work properly.
        (A) I did "modprobe sg" and it succeeded
        (B) I did "modprobe ppscsi" and it succeeded

(3) When I attempted to do a "modprobe epst" I get the following output
on my terminal:

epst.1: epst 0.91 (0.91), Shuttle EPST at 0x378 mode 0 (Nybble) dly 1

I'm not sure what all of this means. I have my parallel port set to ECP
right now, but I'm going to reboot and check out what happens when I
switch to EPP or Bi-Directional. Anyone know what all of this means?
