Basically, we might need to add support for this remote in the hid-sony
driver.

Can you attach the full output of hid-recorder (from the hid-tools[3]
repository) when you press all of these buttons?

This should give us enough information to reply the event sequence
locally and fix the drivers if we need.

Sure thing!

The remote looks like this:
https://www.pdp.com/universal-media-remote-for-playstationr4

hid-recorder output:

Thanks for the logs (though your email client mangled the long lines,
but not an issue TBH).

So this device is not known to the HID stack nor hid-sony or hid-playstation.
We will need to add a special case in one of those 2 drivers because
as you realized, the way these keys are used is not standard.

But I'd like to compare these logs to the PS5 remote that I have here.
Maybe the proprietary fields 0xff000021 is something common in the
PS4/PS5 world.

Also, what happens if you press 2 "special" keys at the same time
(pause and enter for example)?

However, I can not promise I'll work on that tomorrow. And then I'll
take a year end break.

If you don't see anything coming from me tomorrow or in early January,
feel free to re-raise this thread.

Cheers,
Benjamin
