Steam Link - USB devices visible but not passing through

https://i.imgur.com/vISg0Gg.png

Trying to get the paid Steam Link VH program to work. My USB devices are visible on the PC, but aren't quite passing through - testing a controller and a bluetooth dongle, the controller shuts off (and disconnects from the SL's standard functionality) and my computer doesn't get bluetooth functionality.

I saw in other support posts that there might be an exclamation mark in the Device Manager, so I've found that. The status of the flagged eXtensible Host Controller is as follows:

01802441
DN_ROOT_ENUMERATED
DN_DRIVER_BLOCKED
DN_HAS_PROBLEM
DN_DISABLEABLE
DN_NT_ENUMERATOR
DN_NT_DRIVER

It appears to be up to date. Any help?
