Ok.

Please clarify under which circumstances you experience the problem.

You have so far mentioned:

building libusb from source on Gentoo
running Windows on hardware
running Windows in VirtualBox (on Gentoo? maybe also on Windows?)

It would seem to me that you're reporting a problem with USB in
Windows in VirtualBox on Linux behaving different from USB in Windows
on hardware.

This would be about Linux libusb support. Please provide usbmon logs
in that case.

I have heard a lot of nonsense failures with VirtualBox so I am
thoroughly unimpressed by it's capabilities in general and not at all
surprised if it is the cause of the problem, but let's find out the
details and I'll try to avoid jumping to a conclusion. :)
