Did you close Qcma before running it? If usb device session is held by Qcma, finalhe cannot open it then.

By the way, linux usb device permission is default to root-only, you should run finalhe from sudo or root user, or you should put config file in /etc/udev/rules.d/ to set permission individually, check this tutorial
