Again, I agree that hardware compatibility issues suck... Personally, I think life's too short to live with glitches like that - ASMedia chips are used in a lot of PCIe USB cards these days as well, but I've had good luck w/ Renasas cards in the recent past (when I was running VFIO). These USB cards are all pretty cheap ($20-40), so I'd order a few to try and keep the one that works the best.
