Support for Poseidon ZX Illuminated - can't get Cmd key to work.

[GrubLord]

Hi there,

Thank you for your excellent project - it's helped me get the Poseidon ZX Illuminated keyboard almost functional. The only remaining issue is that the command-key doesn't work, which sadly I haven't been able to find a fix for (my workaround at the moment has been to switch it with the less-useful Option/Alt key in the Keyboard control panel).

Here's my generated yaml file for the keyboard:

Could I get your help with the final step of making that final button work?

Hello,

In these cases we need to see what the raw reports from the keyboard look like when sending the command key. There's a hid_report_dumper directory with a simple, but unpolished, utility to do so.

Thanks kindly for getting back to me - sadly, I wasn't able to get your utility to print out anything much except "Seized 0 devices (3 failed)".

Taking over the raw keyboard devices requires root privileges, without which is one way it might fail to seize the devices. Did you run with sudo?

No, I hadn't, and doing this actually helped me to resolve the problem myself: turns out there is a button on the keyboard which doesn't seem to do anything, but its effect is to make the Windows key register as Ctrl instead... for some reason. I guess to prevent it booting you out of a game.

So actually using the yaml file from above, along with your code as-is, works fine, as long as that key is kept appropriately toggled.

Thanks again for your project. It's been really helpful!
