Arria 10 GX Dev Board: USB-Blaster plugged into JTAG port can't access JTAG chain?

[Altera_Forum]

My Arria 10 GX dev. board works fine as long as I am accessing the JTAG chain using the USB port on the front end of the board (where the micro-USB cable plugs in). But, if I try to use a USB-Blaster plugged into the JTAG port (J17) I get the error "can't access JTAG chain." I've tried both orientations with the same results. I've checked the switches on SW4 and they are still in the default setting. Is there another switch I need to toggle?

Does your computer see the USB Blaster? Have you installed the driver? What shows up in the Quartus Programmer?
