I know this isn't the desired answer, but my strategy (a few years ago, on Raspberry Pi, haven't tried HID since then) was to launch a python script to listen for HID messages, then route them via UDP into a local port on which Pd would listen and consume the messages. I don't recall if I had to do some message unpacking in the python script or if I could just route the raw data and unpack everything in Pd.

hmm, well, tried building hid and it's not that easy, not sure I can go that route :)

I can take the request to work on a new/modern 'hid' object into ELSE (not necessarily a copy/clone of this) so we have something like that available for all platforms and modern systems. Please open a request at https://github.com/porres/pd-else

Hi Phil,

A search on Deken

brings up some results which might depend on the OS you are using.
