Ah, I'd assumed it was there to provide a centralized way of discovering
what was there.  I guess it's just a matter of scanning your way through
the contents of /sys/class/input (and equivalent iio) then to find out
what is present and what is supported by each device.

Messier in a sense but guess it will work.

Ah well,
