Actually there's noone else but me providing Windows binaries.el_nihilo:
Now that the Win x64 patches have been integrated in both libftdi and OpenOCD, I’m hoping that the regular distributors of the Windows binaries can provide both a 32 and 64 bit version for people who don’t want to recompile their own.
If you’d be willing to test the installers that I could produce, then I could post x64 version along with 32-bit one on my website. I don’t have a 64-bit system to test whether everything is fine.
If the Wiggler cannot be used right now, than we must wait for someone to test and fix that <:If GiveIO-32 is open source as libusb-win32 is, you can probably apply the same trick to get a working 64 bit Windows driver (that you’ll have to self-sign to install, but that’s a different issue). Else, I’m pretty sure that someone with a Wiggler and running 64-bit Windows will be as annoyed as I was with the FTDI thing and post a tutorial.
4/3!!
