I guess, the
pc doesn't see the USB Blaster?
In this case, does the USB device show in system control manager? The 93C46 configuration EEPROM may be corrupted, then it would be displayed as default FTDI device instead. If no USB device shows at all, it's likely a hardware defect, including possible missing 5V power supply. If an USB Blaster is shown, but doesn't work, the CPLD may have been reprogrammed. It can be restored to factory default configuration with a standard Altera programming cable.
