To the poster have usb-blaster problems...

1. the driver is in the c/altera/<quartus II>/drivers folder.

****NOTE***** this is VERY import. If you have loaded more then one version of quartus and try to program using a lower version there is a chance the usb-blaster driver will not show up!!!

ex: I have quartus II 9.0 and installed the usb-blaster driver from that installations driver folder. I also have quartus ii 7.2 installed.

I can see the usb-blaster from the quartus ii 9.0 programmer but NOT the quartus ii 7.2 programmer. I suspect the reason is there was a change in the 9.0 driver and since that is the one I installed the 7.2 programmer does not see it.
