USB Blaster has stopped working

I am running Quartus 16.1 standard on Windows 10, and have been debugging my firmware with SignalTap II connected through the USB-Blaster.  This has worked fine up until last night when it could no longer find the device.  I've tried different boards, I've tried a different USB blaster.  Nothing works.  If I go to the programming tool and debug the JTAG chain it shows the expected device (Cyclone V SX) and an unknown device.  It seems to be misreading the SOC?  What could have changed?  I've tried installing v20.1 but that USB Blaster driver won't install.

Any clues?
