Actually, FC6 might detect jtag without changing udev rules. The jtag got detected sometime with root account. I have to disable SELinux to run nios2-configure-sof. I tried changing the mode to 0666 in 50-udev.rules to get user access. Sometime it works, but mostly fails.

There is no /etc/hotplug dir in FC6. The /etc/udev rules changed a lot from RHEL4. In FC6, the udev add the jtag as /dev/bus/usb/004/002 dev, the bus number may be different for different usb ports. I think you should not name the dev as "usbblaster".
