Hi all,
one of the biggest shortcomings of the above WebHID-based approach is its currently “sparse” support by various browser families.

I have filed an “idea” (see below) with the Mozilla development team through their idea submission channel, asking for WebHID support in Firefox, too.
If you feel this idea deserves some traction, your comment or like may make a difference in the allocation of Mozilla development resources.
