17 years agoI once had a problem similar to this. I installed the quartus, installed the usbblaster from it's driver directory and some times later installed another version(8.0), so I removed the old version and usb blaster didn't work anymore.
it turned out that by removing a driver's directory for usbblaster, it didn't work any longer. ( though the driver program always should copy it files to windows directory.) by installing the usbblaster drivers from the latest version, the problem dissapeared. I hope this works for you.
