Quartus does not find device

Hi Chorizo,

You can check out this installation guide for USB Blaster: https://www.altera.com/support/support-resources/download/drivers/usb-blaster/dri-usb-blaster-vista.html. If the "found new hardware" message does not appear then you can go to device manager in your PC and see if the system manage to recognize the USB Blaster. If yes then you can proceed to installation following the guide. Good luck!
