That's pretty much ok.
I wouldn't (and I don't) put Physical maximum in. That complicates things.
Without that, 2048 means the center of the screen no matter how big it is.
Once you start putting in Physical maximum in, 2048 means 6" down on a display that might not even be that big.
OTOH, they do specify the units as
cubic inches, so it's probably ignored anyway.
Usage 0x32 & 0x42 on the digitizer are correct.
I'd guess that hid.ko is mangling that and that evtest is working correctly.
In any case, it looks like it sends two HID reports, 0x03 (keys) and 0x02 (digitizer) all the time.
Did you try playing with all the modes on the ring?
It seems complicated to me.
