USB versus SMP and Epson printers (again).

[Frank Mayhar]

I sent this to -hackers and was met with resounding utter, profound silence.
Maybe it will be better targeted here, instead.

On Monday I received my brand-new Epson C82 printer, a replacement for a
900N with a dead print head.  I had already configured CUPS so I imagined
that I would just hook it up with USB and everything would be happy.

Well, that's not quite how it turned out.

I tried two different machines, both with Tyan dual-CPU motherboards.  One
is a Thunder 2500 (S1867) with dual PIII 866, my gateway/fax/server
box and the one I preferred.  The other is my main desktop box, a Tiger
MPX (2466N-4M) with dual Athlon MP 1900+.  Both displayed essentially
the same problem, although the Tiger MPX seemed to come a little bit
closer to working than the Thunder 2500.

Basically, although usbdevs would show the device, when I tried to do,
say, an 'escputil -s -r /dev/ulpt0' (to show the ink levels), the process
would seem to send something to the printer (I say "seem to" because I
saw no evidence of it on the printer side), then sit in the USB code
forever, timing out and looping.

On the Tiger MPX I did see the "port disabled" message when I connected
the printer (although nothing when I disconnected it).  The Thunder 2500
didn't do that much.

I've attached the dmesg from the Thunder 2500; I don't have one handy
for the MPX.  If anyone can give me any hints about this, I would be
very grateful.  Thanks.
