Hi,
I'm having maybe similar problem. I just upgrade my box from old EMC1
and new hardware (same parallel port card). I'm running EMC2.1 Ubuntu
and having several problems. First when I boot I have not parallel ports
visible. After boot "dmesg | grep par" yields:
[ 63.987586] ppdev: user-space parallel port driver
After reading various sites and emails I manually adding the device
"modprobe -i parport_pc" at the shell. Now "dmesg | grep par" gives:
[ 63.987586] ppdev: user-space parallel port driver
[ 1211.925716] parport: PnPBIOS parport detected.
[ 1211.925785] parport0: PC-style at 0x378 (0x778), irq 7, dma 3
[PCSPP,TRISTATE,COMPAT,ECP,DMA]
[ 1212.007775] lp0: using parport0 (interrupt-driven).
[ 1212.007880] PCI parallel port detected: 14d2:8001, I/O at
0xdd00(0xde00)
[ 1212.007908] parport1: PC-style at 0xdd00 (0xde00) [PCSPP,TRISTATE]
[ 1212.089703] lp1: using parport1 (polling).
OK so that's one problem hacked (I think). So question: how do I get it
to do that automatically at boot?
Now I set up the demo stepper_mill files. And I edit the
standard_pinout.hal for the 2nd parport:
loadrt hal_parport cfg="0xdd00"
Next start EMC2.1 with stepper_mill and I get the EMC error dialog when
the follow (abridged) messages:

I'm guessing this is related to my first problem, but hoping someone out
there can point me in the right direction.
