Some GPUs have USB and often you can passthrough an internal USB controller that
is provided by the CPU. Those usually work with passthrough.

Please search the internet/forums for a USB controller that is known to work with passthrough.
Many cheap devices use a USB-chip that does not reset properly.  Sometimes manufacturers change 
the chip without warning for a cheaper one. Level1techs forum might help:

Sorry, but I have no experience with that one. Check what chip it uses internally.

Best of luck on your hunt for the right USB controller.
