Hi Jon,
Hmm - yours says " Kernel modules: parport_pc” whereas my only states: "Kernel
driver in use: parport_pc”.
So I guess you are saying it has to be one of the following then:
Region 0: I/O ports at c030 [size=8]
Region 1: I/O ports at c020 [size=4]
Region 2: I/O ports at c000 [size=32]
But I get nothing on any of them.
jeshua@cncBot:~$ sudo ./pcisetup c030
io addr = c030

For my last SIIG card (also showed c030, that is what I used in fact), but I
didn’t use the pcisetup command, I used this utility someone on this list
pointed me to and the magic command was:
sudo ./showport C020 C030 e
Based on my shell history, it looks like I used trial and error to come up with
those addresses. I am not sure who wrote it - they don’t have their name in the
source but it is here:
http://glassprinted.com/showport.c.txt
The nice thing about the showport command is it flashed parport to stay in
extended mode even on reboot. Well that is, until the Big Zap, then I had to
run that showport command every reboot - which lead me to suspect the parport
over the cable even more.

The USC is brand new that you just tested. When I got it, it was working
intermittently so I thought we figured it either had to have been the old PCI
Parport card or the cable.
The cable I ordered from you, but do you really think the whole cable could
have got fried? I will test all the pins if you think so.
But - if the cable is bad - it was at least letting me talk to the USC - albeit
unreliably - however now with the new card nothing. I can swap the old card
back in to see if it still can see it (I suspect that it will). Let me know if
you think that would be helpful.
When I power it on, yes I get a red flash then go out to a solid green beside
it; only when the power is also connected. When just the parport cable is
plugged in (no 12v to the USC) I get no lights on the board, which IIRC, is how
it was in the past when it was woking until I set the card to epp then I would
get dim green (and maybe dim red) lights...
