Feat: Add support for SteelSeries Arctis Nova 3P Wireless - #417

I first tried seeing if the implementation of SteelSeries Arctis Nova 3 works for this model as well, but it doesn't.

It seems like most (if not all) of the commands for each capability are the same, except without the 0x06 byte at the beginning. So you might be able to copy most of the code from the Arctis Nova 3 implementation for the Nova 3P (though I already saw the latter was a bit more capable, such as supporting more sidetone levels).

Yeah, I copied most of the code

Support for Linux works fine on my end.

Unfortunately inside my Windows VM things don't work (I tried all Usage-Page + Interface combos as reported by headsetcontrol --dev -- --list). There seems to be an issue with how I use hid_send_feature_report because inside WireShark I see the packets have 1060 length.

Windows support is a bit tricky, it expects the exact same length.
Here it seems to be overwritten:
The FeatureReport seems to be supposed to be longer

I think we can merge anyways, we just need to maybe include some message or at least a comment that windows seems to not quite work yet with that implementation

Alright, where should I write the message/comment?

Are all functions erroring out or only specific?

From what I recall, nothing works on windows and they don't error out but instead just don't have any effects.
