[Qemu-devel] [PATCH] usb: Support compilation without poll.h

[Stefan Weil]

This is a hack to support compilation with Mingw-w64 which provides
a libusb-1.0 package, but no poll.h.

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
