So the Renesas card is garbage. > Hmm, let me offer another data point; if I assign the onboard ASMedia USB3 controller to my VM, I often get hangs when OVMF enumerates attached devices and it's a crap shoot whether devices will work after a VM reboot. On the other hand, my Renesas card works much more reliably. However, I've also found that TI based USB3 chips work far more reliably than either of those for non-VM, bare metal use (no VM experience on those). The early versions of the Renesas chips are pretty crappy, but I infer that newer ones are more well behaved. Personally I'm not a fan of any ASMedia components and avoid them in my purchasing decisions. Thanks, Alex
