Unfortunately none of above methods currently works.

USB passthrough isn't implemented for Windows yet, and it is quite
unlikely we (as core Qubes OS team) will work on this in the near
future. But some community contribution could help here. In theory all
the building blocks are there:
1. USBIP Windows drivers: usbip.sourceforge.net
2. Qrexec agent for Windows - part of Qubes Windows Tools

The missing part is connecting those two together.

As for passing through the whole USB controller, it is broken currently:
We'll work on this some more this month and hopefully fix it.
