USBblaster does not show up in Quartus

Just a note on how I solved this problem..

It was the driver that came with 11.1sp2...

I had the same problem above, and tried all the different suggestions:

- using older DLLs

- downloading the '64bit version' (I never found a true 64bit version)

- using v10.0 programmer

- re-installing the driver

- checking that other applications weren't trying to use port 1309

So I eventually just downloaded the USBBlaster driver zip from Altera website.

<url deleted because I don't have url posting privileges - you can find it by googling "usbblaster driver windows 7">

and reinstalled the driver with those drivers and it's working now.

So if you have 11.1sp2, that might be your problem.
