The usb blaster appears in device manager with the '?' next to it. The common thread is that they are all running the 20H2 build of Windows10 圆4 This is consistent across all the machines I've tried so far, including a fresh out of the box (non domain joined Dell machine). Running dpinst.exe gives a "cannot complete the device driver installation" with the 4 parts of the drivers suite (APU_USB, oemsetup.inf, USB-Blaster device driver, WinUSB JTAG cable showing "Install failed."Ĭhecked the event viewer logs and no entries that I can see other than a consent.exe file getting run which I assume has to do with running this process as an administrator.

This is using the 20.1.1 version of Quartus Prime

Hi, I have a consistent issue when trying to install the USB-Blaster drivers on Windows 10, 20H2
