This is a hack to support compilation with Mingw-w64 which provides
a libusb-1.0 package, but no poll.h.
Signed-off-by: Stefan Weil <address@hidden>

I did not test whether this USB host code works on Windows,
but at least it compiles with this hack.
Suggestions for a better fix are welcome.
Regards,
Stefan
