Viper ultimate dongle disconnecting and connecting every time

Have you tried plug usb dongle directly into motherboard (different port) or using it via USB extension?

I tried plug the dongle into other ports in pc but continues the same thing

I uninstalled all drivers of the mouse and is the same thing, i tried disable power saving in the usb settings in power plan but didnt result , I disable the power save in ports usb in device manager but is the same thing.

Same problem here since 2 weeks! I have always used the dongle in my PC and my laptop - no problems. I then unpluged it for a week due to traveling and when I came back, I had the same problem with both devices. Both run on windows 10, the dongle works in none of their usb ports (other mouses using dongles work just fine and my razer mouse works fine with cable). I deinstalled all drivers and synapse 3 and re-installed them. However, as the  drivers require a stable dongle to mouse connection (which isn’t given), I can not install the mouse drivers and it drives me crazy! Especially, as I still have warranty (bought it online in August 2023). Optically, the dongle works just fine and I did not install any updates or so while I was gone. So I have no clue at all, what’s going on

Had the same problem for 4 months and tried absolutely anything and everything, support were completely useless in handling the issue asside from telling me right away that I should go out and buy a new dongle. Switched to the logitech pro X and never looked back. This mouse isn’t worth the hassle that it comes with when it comes to Razer support.
