You must install the Altera® USB-BlasterTM or Altera USB-Blaster II download cable driver before you can use it to program devices with Quartus® II software.

The first time the USB-Blaster download cable is plugged in, the Windows Found New Hardware dialog box prompts you to install the driver. (Note: Do not use the Add Hardware Wizard from the Control Panel.)

The USB-Blaster II device drivers require manual installation so that the cable will be properly recognized. Refer to the instructions below.

The Altera On-Board USB-Blaster II cable appears as Altera USB-Blaster (unconfigured) when first attached to your system. After it has been configured by the Quartus II software, it will appear as Altera USB-Blaster II (JTAG interface) and then Altera USB-Blaster II (SystemConsole interface). You might need to install drivers for each of these interfaces; follow the steps below to install the drivers.
