I've followed the guide to the letter and Atmel Studio 6 still refuses to recognise USBTinyISP.
So far i have:
Installed latest drivers for Win 7 64 from the downloads page [http://www.ladyada.net/make/usbtinyisp/usbtinyisp_libusb-win32_1.2.1.0.zip]
Installed AVRDude from latest sourceforge [avrdude version 5.10, URL: <http://savannah.nongnu.org/projects/avrdude/>]
Istalled com0com and set up 2 com redirects COM8-COM19 and COM9-COM19

Installed usbtiny500 set to COM9 and received Status:Ready

However, even after this Atmel Studio 6 sees nothing:

Has anyone got anything that they can offer in the way of advice for this? It's really annoying that the one thing I bought it for, which it advertises it should be capable of doing, it can't.
