Hi,

I'd hate to say it, but that's exactly my experience with USB3 
forwarding in VMs. It's just not mature enough. Not with KVM/Qemu, nor 
with Virtualbox. Haven't tried VMWare, though, but wasn't expecting wonders.

You can try to forward your PCIe USB3 adapter rather than letting your 
virtualizer forward single ports, but that'll take away control from all 
the devices connected to that USB3 host from the host OS, which is 
pretty bad if that USB3 controller is effectively the main controller 
that drives e.g. the USB port your mouse & keyboard connect to, and it 
didn't work for a plug-in USB3 PCIe card on my laptop.

Best regards,
Marcus
