USB Blaster JTAG chain broken

Same configuration as yours. Probably same reason: http://askubuntu.com/questions/288821/how-do-i-resolve-a-cannot-open-shared-object-file-libudev-so-0-error

I'm using Ubuntu14.04 and quartus14.1. When I run jtagconfig, I get

:

$ jtagconfig

1) USB-Blaster [3-6]

Unable to read device chain - JTAG chain broken

The hardware is correct because I can read the JTAG chain using a old PC.

Some extra information:

$ cat /etc/udev/rules.d/51-usbblaster.rules# USB-Blaster

# # from http://www.fpga-dev.com/altera-usb-blaster-with-ubuntu/

# For Altera USB-Blaster permissions.

SUBSYSTEM=="usb",

ENV{DEVTYPE}=="usb_device",

ATTR{idVendor}=="09fb",

ATTR{idProduct}=="6001",

MODE="0666",

NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}",

RUN+="/bin/chmod 0666 %c"

$ ls -l /etc/jtagd/pgm_parts.txt

-rw-r--r-- 1 root root 921110 Jan 12 12:54 /etc/jtagd/pgm_parts.txt

I have also re-run:

$ sudo udevadm control --reload

But nothing help!

Any tips?
