So I for example quite often make use of the HID debugfs entries both for
reading the descriptor, and also for analyzing the parsed events (which
appear there as well).
Surely it can be moved whereever else (where?), but it seems to fit to
debugfs (it's used solely to debug dysfunctional devices / linux with
those devices), and provides exactly the data you need from the owner of
the system to provide in order to be able to debug remotely.
