I know this post is a bit old, but i stumbled upon exactly this issue and figured it deserved a reply.

The permissions change you have listed is one that is floating around the internet, but when i used those same permissions the jtag server had the same lockup behavior.

Instead use these rule commands

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6001", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6002", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6003", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6010", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="09fb", ATTR{idProduct}=="6810", MODE="0666"

and it will work.

If you look at it this makes a bit more sense, what is all that extra stuff doing anyway?
