I was happy to find the driver so I figured I wasn't the only one looking.
And for clarity, the devil is in the details...
Just as you wrote you used a USB-2.0 Type-A cable and that works (I tried multiple cables and all works).
When I initially tested I used USB-C to USB-C cables directly to my Mac. I tested with both the "charge cable" and a Thunderbolt-3 cable... none of them worked (nothing was discovered when running dmesg).
A bit annoying having to go from USB-C to USB-A to USB-C, but I guess it has to do with "down-grading" to USB-2.0.
