USB-BlasterII [3-11] Unable to read device chain- JTAG chain broken

I am having issues getting my Cyclone V GT dev kit to connect with my computer with the built in USB Blaster II. My computer is running Centos6.8. I have installed Quartus II 15.0.

I have followed the instructions at https://www.altera.com/en_us/pdfs/literature/ug/ug_usb_blstr_ii_cable.pdf for Installing the USB-Blaster II Driver on Linux Systems by changing the /etc/udev/rules.d/51-usbblaster.rules file.

I then rebooted. When I run:

sudo killall -9 jtagd

sudo jtagd

jtagconfig

I get:

1) USB-BlasterII [3-11]

Unable to read device chain - JTAG chain broken

I know the computer is able to recognize the USB port; when I type lsusb, I get:

Bus 003 Device 005: ID 09fb:6010 Altera

Does anyone have an idea what the problem may be? It wouldn't surprise me if I was missing some simple dependency, but I can't find a list of the dependencies that are needed anywhere.

Thanks,

joe
