Can I use a WCH Parallel Port Card?

Hi,

I'm trying to get LinuxCNC running for my CNC using this Parallel Port Card (www.amazon.de/gp/product/B00GT686IW/ref=...06_s00?ie=UTF8&psc=1). I read on this website (wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH) that the card may not be working, but There was some kind of Kernel change so it might still work now, even though it shows up as a Serial Device? I don't really understand what that all means, could somebody clarify it for me?

Thanks alot,

Max

Also, if its not possible, do you think this card would work? (www.amazon.de/DIGITUS-Interface-Schnitts...omputers&sr=1-5&th=1)

Thanks for the quick reply. Do you know how I can be sure if the card is working? I'm not able to install any drivers from the attatched CD, but the device is showing up as Serial Controller (I guess that's bad?!).

This gives back:

Kernel driver in use: parport_pc
Kernel modules: parport_pc, parport_serial




Without the grep I get the following:

line 02.00 is the parallel port card. I don't know if that is whats its supposed to say....

Thanks for your help, I think it would have worked, but the card had very bad manufacturing tolerances and didn't really fit into the pcie slot. I bought a new card now and it works just fine.
