Out of pure curiosity, how does this manifest in CPU consumption? USB 1 and 2 are CPU hungry when virtualized. USB 3 / XHCI is more amicable and (as far as I know) the answer for the "my virtual USB devices consume too much CPU even when idle" problem. I wonder if increasing the XHCI polling rate 50-fold will impact VMs visibly. (Admittedly, a VM spends a fraction of its lifetime executing OVMF, hence "pure curiosity" on my part.) Gerd, what's your take?
