There is a new development on the libusb 1.0 for Windows front now that
libusb 1.0 already works under Linux and Mac OS X. Now the libusb-winusb
branch reached beta status. This may be a good alternative to the libusb-win32
project which has not moved for years.

http://libusb.org/wiki/windows_backend

The benefits of this WinUSB backend is that it will work for 64bit Windows
like Vista and Windows 7. The WinUSB backend will not support isochronous
transfer, but that is not a problem for use with OpenOCD.

libusb-winusb will be integrated to the main libusb-1.0 tree (using git). Once
it is mature, I think it will be very good replacement for libusb-win32
for libftdi and OpenOCD project.

Interestingly, one of the tools the author (Pete) used for testing is OpenOCD
with the FTDI based dongle. He is modifying libftdi to use his libusb-winusb
and it seems that OpenOCD still works. I will give it a try later.

Please try this branch if you are interested.
