Here's the report from my older Siig card :
04:02.0 Parallel controller: Siig Inc CyberParallel (2-port)
(prog-if 02)
Subsystem: Siig Inc CyberParallel (2-port)
Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV-
VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Interrupt: pin A routed to IRQ 18
Region 0: I/O ports at dc70 [size=8]
Region 2: I/O ports at dc78 [size=8]
Capabilities: [a0] Power Management version 1
Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA
PME(D0-,D1-,D2-,D3hot-,D3cold-)
Status: D0 PME-Enable- DSel=0 DScale=0 PME-
Kernel driver in use: parport_pc
Kernel modules: parport_pc
DC70 and DC78 are the two data ports addresses for the two
parallel ports it provides.
Now, when I boot this system, I have to run the pcisetup
program before the diags will work, and I think I use the
dc70 address and it figures out the correct ECR address from
that. LinuxCNC handles the EPP mode selection
automatically, I don't have to do anything.
Are you really sure your USC board is working? Possibly,
something happened to either it or your IEEE-1284 cable. It
WAS working a few days ago, and then SOMETHING quit. You
assumed it was the parallel port, but maybe it was some
other unit. When you power it on, does the Load Fail LED
flash for about 0.1 second and then go out?
