Synapse 3 & Legacy 2.0 don't mesh

I recently bought a BlackWidow X Tournament Edition Chroma to go with my Naga Trinity and my Tartarus Pro. However, ever since plugging it in my chroma is all over the place, my devices constantly stop working and freak out, it's infuriating. It shouldn't be this hard to make your own accessories mesh. Anyone else have this issue or know of a solution? If I can't figure it out I'm just going to go full Steel Series instead lol.
