Nios2eds can't detect usbblaster

My os: Ubuntu 12.04 lts

After I configured the .sof file for my de1 board, I tried to program the "hello_world_small" template to the board but i got

"no nios ii target connection paths were located. check connections and that a nios ii .sof is downloaded."

My SOPC design is the following:

    Hi.

    Delete the software and create it one more time. If it doesn't help regenerate nios2 system and recompile Quartus II project, then create your Hello world software. I face the same problem from time to time and don't know another way to solve it) Have a nice day.

    Thank for help

    I recompile software, hardware many times, but i get the same problem.

    I install "Altera Quartus Usb blaster" by creating /etc/udev/rules.d/51-usbblaster.rules:

    # Altera USB-Blaster rule to set mode to 666.

    SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="09fb", ATTRS{idProduct}=="6001", MODE="0666", NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", RUN+="/bin/chmod 0666 %c"

    Can you check that FPGA is successfully configured? For example, leds start blinking or conversely stop blinking
