echo 'attr{idvendor}=="09fb", attr{idproduct}=="6001" mode="666"' ya its showing ,after that i reboot my machine also. - Altera_Forum
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. - Altera_Forum
Now i changed the 51-usbblaster.rules files, but ....

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. - Altera_Forum
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.
