Just got mine in the post, thanks Sidehack!
Just in case anyone else gets this issue..
I wanted to try my sticks in Windows before I set up my Pi at a later date. I installed Zadig and the special cgminer (in 1st post of this thread) but I had to install a zlib1.dll into system32 before cgminer would run. Secondly I was getting error "libusb_sucess" in the cgminer, I had to go to (Win10) control panel>hardware and sound>power options>change plan settings>change advanced power settings>usb settings>usb selective suspend setting>disabled.
