Install parallel port

I am desperately trying to install an external parallel card.
My computer does not have an internal parallel port, so I inserted an external card
This card has a "mcs9865" chip.

The instruction "lspci -v" gives this;

02:04.0 Parallel controller: MosChip Semiconductor Technology Ltd. PCI 9865 Multi-I/O Controller (prog-if 03 [IEEE1284])
Subsystem: Device a000:2000
Flags: bus master, medium devsel, latency 32, IRQ 5
I/O ports at ef00
I/O ports at ee00
Memory at fdefe000 (32-bit, non-prefetchable) [size=4K]
Memory at fdefd000 (32-bit, non-prefetchable) [size=4K]
Capabilities: <access denied>
Kernel modules: parport_pc

I have tried with;
loadrt hal_parport cfg="0 out"
loadrt hal_parport cfg="0"
loadrt hal_parport cfg="0xef00 out"
loadrt hal_parport cfg="0xef00"
loadrt hal_parport cfg="0xee00 out"
loadrt hal_parport cfg="0xee00"

but when i start the cnc i get the debug info

"Linux parallel port xxxxx not found"

Anyone any idea how I can fix it?

External? Via USB or how is it connected to PC?

I think "Linux parallel port xxxxx not found" is just a warning
LinuxCNC may still work if you provide the actual card address

(since the actual card access is direct to hardware)

By external I don't mean standard on the motherboard, but plugged into a PCI slot.

Hi Grotius,
I have already followed that method, but it does not work
