So I have been using a Razer Chroma Naga Epic for about the last year and a half and was recently gifted a Razer Deathadder Chroma from a friend. I plugged in the Razer Deathadder while keeping the Naga docked since I thought I could make it my editing mouse and the Deathadder could be my gaming mouse. When I did this I found that Synapse no longer would open and failed to do anything. It wasn't until I unplugged my Naga that I was able to edit my settings and more with my Deathadder. I can't be the only person who uses 2 Chroma mice on one rig am I? Why does it do this? Note* I also have a Kraken 7.1 Chroma and Blackwidow V1 Chroma on this device.
