Ah yes, that is true libusb does not support poll on windows (since
there is no such thing under windows).

No, I don't think it is likely this will get fixed in qemu, so usb-redirection
will simply not be supported under Windows.

Fixing the compile error is not going to help (much), you will end up with code
which does not call libusb_handle_events when it should, so things won't work.
