I have Kraken headset and a Naga. Both have been working perfectly fine with Synapse. 100% worked every day all day. Now for whatever reason the mouse stopped showing up. The mouse works. The computer picks it up and even recognizes that it is a Razer Naga. Things I have done: Unplugged/plugged in different USB port Plugged into different computer (downloaded synapse. It picked up the mouse!) Reinstalled Synapse ( deleted everything razer related, hidden files, extra files in other folders) Deleted drivers/reinstalled drivers/updated drivers/downgraded drivers Messed with the firewall while reinstalling Synapse/downloading drivers When I finished with each of these processes and plugged my mouse and headset into the computer, the computer would pick up the headset and try to install synapse, synapse gets installed shows the headset and it works beautifully. I look for the mouse. My computer says it's there. Even shows that it is a razer mouse but synapse doesn't. After a few more tries I am throwing in the towel and using the mouse as is with no Synapse interactions. All the Chroma works which is nice. I can't use any of the macros and neat stuff I had on it which is a huge bummer.
