Yes there is an example in libusb-win32 which does this. Please
take a look at this. It is also included in the source package download.

No, libusb0.sys is obvously better than winusb.sys. :-)

I am biased as I am the admin of libusb-win32 project.
WinUSB is not bad either but libusb0.sys has features
which WinUSB does not support.

1) libusb0.sys supports isoc transfer, WinUSB does not
support isoc transfer
2) libusb0.sys supports Win2k, Windows XP64 and Windows
2003, winusb.sys does not support these OS.
3) libusb0.sys supports USB device reset whereas
WinUSB does not support this feature

That being said, if you want to use libusb-1.0 Windows
backend right now, you have to use WinUSB since the
current Windows backend only supports WinUSB.
We are working on a libusb0.sys and libusbk.sys
backend so in the future you can use libusbk.sys
or libusb0.sys with libusb-1.0 Windows backend.

libusbk.sys is the next-gen libusb0.sys. It is still
under active development.
