SteelSeries Sensei mouse and mumble issues

[Granine]

So I just got myself a SteelSeries Sensei raw input mouse and ever since my mumble starts to cut out whenever I'm trying to use the VoIP. If I go to use local or squad chat and fire at the same time the VoIP cuts out until I let off the fire button. I'm not sure exactly why it's doing this but any insight would be greatly appreciated.

Update:

So now it seems the mumble VoIP cuts out with the previous mouse I was using as well. Upon holding down left MB it'll cut the communications until I let go.

That is an exclusivity issue,
