So I checked the razer website here:
Fastest Wireless Gaming Technology | Razer HyperSpeed

When I click on “See Supported Mice” under Step One, it says that the Razer Viper Ultimate now supports Hyperspeed/Multipoint.

I have a Razer BlackWidow V3 Pro and I’d like to pair my mouse with my keyboard’s dongle if that’s possible. How would I do that?
