I have been using the Febsmart usb3 card you mention above for 6 months with zero problems. I've left the vm running for days at a time with no issues. I also use it for VR.

I use it with a USB switch where I plug:

• keyboard
• mouse
• gamepad
• usb headset

& in the usb3 card I plug:

• port 1 of the usb card = usb switch
• port 2 of the usb card = printer
• port 3 of the usb card = Oculus Rift S
• port 4 of the usb card = free at the moment

If I need more usb ports in the vm I also have a 4 port usb3 hub

There seems to be 2 versions of the 4 port Febsmart USB cards - the old mark 1 fire hazzard versions have vertically aligned ports whereas the ok version has horizontally aligned ports (& different circuit protectors)
