There is a warning, not so sure if it is really of importance or not.
The good thing is that ST-Link V2 uses Winusb.sys and libusbx
works out of the box, without the need to switch driver.
(ST-Link V1 uses USB Mass Storage driver).

BTW, xusb's descriptor dumping is a bit ugly.
Here is the output from libusbK's klist.
