You need to ask libusb windows experts, it's a problem on the layer
below OpenOCD, we can't do anything about it, unfortunately. You
should probably file a ticket on their issue tracker.

This exact combination you described worked nicely with windows xp but
somehow more modern versions require replacing driver of composite
device parent. Blame microsoft. You might want to consider using a
standard operating system instead.
