I've got a new model of the 10" HDMI B.
It behaves differently.
First of all - uep seems to take it, which it didn't for any of
the previous displays I'd tested.
I had to remove the driver from the loader.conf to have webcamd attach to it.
webcamd attaches fine and it delivers touch events:

Whatever had been the cause for my previous problem, they obviously
have fixed them in firmware.
