Right, I've got my TZ85As and hobbyking USBasp programmer, I've installed Atmel studio 7 and downloaded and installed a driver for the USBasp (from here: http://www.fischl.de/usbasp/). I've done all my soldering and all looks good. I'm trying to add a target in Atmel studio but nothing is listed under ports, I've been into device manager and can see the USBasp and it says it is working correctly, but even in device manager it is not listed under ports but under 'Atmel USB Devices'. Can anyone work out what I'm doing wrong?
