WinDBG has recently added support for USB2 debugging support. I haven't 
seen it explicitly stated by Microsoft anywhere, but it seems to use the 
"debug port" defined by EHCI. Here is a post:

The debug cable mentioned can be purchased from Mouser for $75:

or here for 80:

For debug targets with their own *device* controller, you may not even 
need the dongle.
