USB is not realtime, which is not important for Mach, but crucial for LinuxCNC. AFAIK Mach sends position commands over usb, those particular cards have a buffer (IIRC 1 to 2 seconds, please correct me, if I am wrong) and some kind of motion control. It just seems so wrong to me as so much things can happen during that period on a fast plasma machine or something similar. Araisrobo have made LinuxCNC to talk to some external card (7i43?) via usb, but I have no idea, how exactly is that done. I guess that searching archives would bring up some more information from Yishin Li.
