So I have a new keyboard, a Nuphy Air75. It's got a 2.4 GHz dongle that I've been trying to figure out on how to increase the polling rate on, as it just drops out sometimes and doesn't pick up more than a handful of keystrokes. I have tried using the Mouse polling rate - ArchWiki page, and nothing really translated well.

Any suggestion would be great.

Looking over Mouse polling rate - ArchWiki again, I went and followed the "Set Polling Interval" instructions while setting the value to 1 for a 1000MHz poling rate and seem to be doing fine now. Will update after work when I have a chance to test if this is actually usable with games but seems fine now.

This was not the fix. I'll update as I continue to test.
