I'm currently having an issue with mine. After a while, I started noticing that I was getting double keystrokes. I recently updated the firmware from version 40 to version 51, as well as updating the software to 2.1.2. Now when I experience duplicate keystrokes, it's 3 at a time instead of just 2. I have noticed that in the Windows Device Manager, my Poseidon Z RGB is showing up as 3 'HID Keyboard Device' devices under the Keyboard category. I've tried uninstalling all HID Keyboard Device listings, and unplugging and plugging the keyboard back in, and all 3 listings come back. I would like to fix this soon, or I might have to find a new keyboard. I'm based in Oregon, USA.
