Usb-blaster Driver for Windows 7 and Windows Vista

You must install the Intel® FPGA USB-Blaster™ or Intel FPGA USB-Blaster II download cable driver before you can use it to program devices with Intel® Quartus® Prime 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 Intel FPGA On-Board USB-Blaster II cable appears as Intel FPGA USB-Blaster (unconfigured) when first attached to your system. After it has been configured by the Intel Quartus Prime software, it will appear as Intel FPGA USB-Blaster II (JTAG interface) and then Intel FPGA USB-Blaster II (System Console interface). You might need to install drivers for each of these interfaces; follow the steps below to install the drivers.

You must have system administration (Administrator) privileges to install the USB-Blaster and USB-Blaster II download cable driver.
