I bought a used viper v3 pro mouse a few weeks back, and just recently bought the hyperpolling dongle but the dongle will not recognize the mouse (the mouse works fine wired) I updated the firmware of the dongle with HyperPollingDeviceFirmwareUpdater from Razers website. This was able to detect the dongle and update, but after the dongle update when it was time to update the mouse it did not detect the mouse.I updated the mouse with ViperV3Pro_00C100C0_FirmwareUpdater. I first used the “just mouse” update option since backthen I did not have the dongle, but now with the dongle I tried to mouse and dongle option but it did not detect the dongle.
Since both devices show up in synapse (different wires ofc) I tried the pair device utility under the hyperpolling dongle which did not detect the mouse.

    I saw a comment implying that the viper v3 pro will only work with the dongle it comes with? 

I would like some assistance if at all possible otherwise im just going to return both and get my money back.
