Hey, so I use Arch as my main OS too. You have to set the udev rules as mentioned in the Usage section of the Github repo of ns-usbloader. One thing that I want to say though is that, it might or might not work without sudo. I use sudo java -jar ns-usbloader-5.2.jar to launch ns-usbloader. You mentioned you installed it through AUR but you could simply download the .jar file from their Github's release section.
