alex@alex:~$ cat /lib/udev/rules.d/51-usbblaster.rules 

 echo 'attr{idvendor}=="09fb", attr{idproduct}=="6001" mode="666"'   ya its showing ,after that i reboot my machine also.

The rules file should not contain "echo". This means that you did not use the file from my zip archive at this post (http://www.alteraforum.com/forum/showpost.php?p=154547&postcount=9) 

 Use the file from the zip file to overwrite the existing 51-usbblaster.rules file and try again.  N.

Now i changed the 51-usbblaster.rules files, but .... 

  alex@alex:~$ cat /lib/udev/rules.d/51-usbblaster.rules  attr{idvendor}=="09fb", attr{idproduct}=="6001", mode="666" alex@alex:~$ jtagconfig 1) usb-blaster variant [7-1]  unable to lock chain (insufficient port permissions)

[Altera_Forum]

Did you reboot after changing the file?

[Altera_Forum]

ya, i reboot the system, but no use, same problem.........

[Altera_Forum]

That should have worked. Maybe you can try one of the other solutions from this thread (http://www.alteraforum.com/forum/showthread.php?t=5893).

In my case usb-blaster is working, in those posts they explained about usb-blaster on uubntu only, really i dont know , what i have to do, nearly one week , i tried but failed. 

can i try it in windows?   Thanks for ur suggestions.

You can always try running everything as root. Just type "sudo su" at the command prompt to become root (that way you don't have to type sudo everytime) and run jtagconfig.

My /etc/rc.local is like ,  

  # !/bin/sh -e# # rc.local# # This script is executed at the end of each multiuser runlevel.# Make sure that the script will "exit 0" on success or any other# value on error.# # In order to enable or disable this script just change the execution# bits.# # By default this script does nothing.    mount --bind /dev/bus /proc/bus ln -s /sys/kernel/debug/usb/devices /proc/bus/usb/devices  /opt/quartus/bin/jtagd exit   Thanks, Alex
