[Feature Request] Can we support SInput compatiblity

[LeeNX]

I have been watching a new HID device been added to SDL called SInput, which has got quite a bit of work of late - libsdl-org/SDL#13343

Looks like a documented way of adding a bunch of support features into at least SDL - https://docs.handheldlegend.com/s/sinput/doc/sinput-hid-protocol-TkPYWlDMAg and even a githib repo - https://github.com/HandHeldLegend/SInput-HID

If SDL supports these features, I bet that Linux and Chrome WebHID support will follow (as open source projects)

for SDL as of today and SDL release v3.2.20 - SInput has not been included in the the release, but is in the main branch. This would be a local compile of SDL to test against.

I think that we would need have Feature Report, with Output Report and callback supports, before we really can add SInput feature set.

For testing, I think we will also need a testing process guide, as I think HID devices, if claimed by host OS, is not accessible or seen as plug-n-play. I belive an ENV is needed to trigger SDL to use already captured HID devices as input devices, but I will investigate.

Interesting

Let me know if anything comes of it

Still have not seen an SDL release that includes SInput support by default, but has raised a few things that we could do before the.

I need to finish #283 for full support, as some features need the Report Feature, not just Output Report.

As per libsdl-org/SDL#14477 (comment)

I think we will see the first beta release with SInput soon. One less thing to compile and test against, so I can move up my list to get around to play with and see what I can get right.

Off to try and finish PR #283
