This is the parallel port (EPP) version. Ah, yes! I know the problems (in a general way) all too well, as I also make a line of boards that use the EPP (IEEE-1284) parallel port. I went through HELL and back around 2004 with cheap motherboards that didn't implement the IEEE-1284 protocol right. Some of them could be fixed with a tweak in my code, some of them were hopeless. At least for my boards, the situation has brightened up a bit, at least if you use recent boards from major manufacturers. I have had stellar luck with older Dell boxes I bought off eBay. But, there are gremlins in these par port implementations, and the FPGA designer has to work his way around them.
