Open the Device Manager, and right-click on the Unknown device under the Other devices branch. Select Update Driver Software. Select Browse my computer for driver software. Enter the location of the Quartus II software USB-Blaster II driver files directory (<Path to Quartus II installation>\drivers\usb-blaster-ii) in the Search for driver software in this location field. Click Next. Click Install in the Would you like to install this device software? Windows security dialog box. Close the Update Driver Software - Altera USB-Blaster II (Unconfigured) successful installation notification. The Device Manager now shows a new branch called JTAG cables with an Altera USB-Blaster II (Unconfigured) node. Open the Quartus II Programmer. Within a few seconds, the JTAG cables branch displays two nodes: Altera USB-Blaster II (JTAG interface) and Altera-USB Blaster II (System Console interface). If that doesn't work, try installing quartus web edition 15.0
