Issues with ThermalTake Pure Plus 12 / USB Fan Controller

I am not able to get my Pure Plus 12 RGB Radiator Fan TT Premium Edition (CL-F063-PL12SW-A) controller to show up in OpenRGB.

It shows up as LEDFanBox in logs:

I have tried adding

SUBSYSTEMS=="usb", ATTR{idVendor}=="264a", ATTR{idProduct}=="2260", TAG+="uaccess"

to 60-openrgb.rules with no effect.

I am running Ubuntu 20.04 and building from master. I tried wiping out my local copy and re-pulling last night to be sure it was not a temporary change.

When I start either as user or root I get the following errors along with some hex output:

$ sudo ./OpenRGB

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

Does OpenRGB not support this controller or am I doing something wrong?
