Do they show driver and module in use?
I would guess at yes... as the flags are only "medium devsel"

Model: PAR5408AXX200
Chipset: Sunix SUN1989
Interface: PCIe
Supports PS/2: YES
Supports EPP: NOT TESTED
Supports IN Mode: YES (in PS/2 Mode)
Supports X Mode: NO (Control port pins voltage drops to ~0,3 V when connected to ground through 470 ohms resistor, but pins states won't change)
Tested OS: linuxcnc-2.8.4 / Debian Buster
Tested Computer: Dell Optiplex 760

thank you guys, you helped me a lot, I realized that these are in fact stepper drivers and motors, the voltage is 45vdc, I will buy a simple stepper driver and try to connect phases a,a+,b,b+ and according to my understanding ``com'' I should short-circuit two pairs (wires) of aCOM and bCOM separately

There is a demo download, ask the guy from Norway to download and test.
If he is hooked on it he should try it.
