    At one point in time since switching from debian to arch I had figured out the extra bits you need to get TrueRNG to work, and I didn’t write it down and subsequently forgot how to do it. After just refiguring it out I thought I’d post it here since I’ll probably forget again.

    wget http://ubld.it/wp-content/uploads/2014/02/TrueRNG-Linux-udev-rules.tar.gz

    tar -zxvf TrueRNG-Linux-udev-rules.tar.gz -C /etc/udev/rules.d/

    *Plug in TrueRNG USB Hardware RNG* <important step sometimes overlooked

    ls -l /dev/TrueRNG

    pacman -Syu rng-tools

    systemctl enable rngd.service

    systemctl start rngd.service

    sudo nano /etc/conf.d/rngd

    RNGD_OPTS=”-o /dev/random -r /dev/TrueRNG”

    thats the basic idea

    Haven’t messed with Arch much, but that sounds about right. Typically the rng-tools daemon (rngd) points to /dev/hwrng by default. So yeah get the udev rules in to make /dev/TrueRNG. Get the rng-tools package. Modify the conf file to point to /dev/TrueRNG.
