Razer DA v3 Pro Dongle KVM Connectivity Problems

I recently got the DeathAdder v3 Pro and have begun using it with my KVM between a Windows PC and a MacBook Pro.

I can use the mouse wirelessly on my Windows machine, switch to MacBook and still use it wirelessly without trouble, but if I try to switch from Mac to Windows, the mouse will not work unless I unplug and plug it back in. So it seems Windows → MacOS works, but MacOS → Windows does not. If I used the mouse wired, there’s no trouble at all.

Is there a setting on Windows causing this? I don’t see why the mouse would be fine to connect when switching to Mac but unable to connect when switching to Windows.

IMPORTANT: I am able to switch flawlessly back and forth with another wireless mouse I have. So I don’t believe the issue is the KVM. For the DeathAdder, I’ve tried wireless with and without the adapter.

Thanks!

      I know this post is a bit old but I have the exact same behavior on my Viper V2 Pro and Blackwidow V3 Mini Hyperspeed (paired on the same dongle). I’ve got a monitor KVM set between my Windows gaming PC and another Windows laptop for work - the PC is connected to KVM via USB 3 and DisplayPort, the laptop is over Thunderbolt 4.

      KVM-switching to the laptop is fine, KVM-switching back to the desktop results in loss of connectivity and I have to power cycle the monitor.

      I believe the DA also uses the same “Hyperspeed” dongle that my BW and Viper use, so I have to wonder if it’s something with that technology. I also have a wired USB headset connected to the same KVM and it has no issues whatsoever.

        I would also like details on this.

        I as assuming a general flaw in Razer USB power handling either in hardware or in Razer Synapse.

        I am using a newly bought DeathStalker V2 (wired keyboard) and a KVM switch to operate my home, Windows 10 PC, and a Windows 11 work PC.

        When switching from one PC to the other, the keyboard seemingly loses power, does not register keypresses, no lighting. When I switch back to the original PC, it again works. If, however, I reconnect the USB cable on the second PC, it now works there (popping up as a device in Razer Synapse), but ceases working on the original PC in the above fashion (and is not anymore listed as a device in Razer Synapse there).
        When I switch from one PC to the other, but that one is off, the keyboard loses power, but when switching back, it again works.

        Please note, that with this KVM switch, other keyboards, such as a Logitech G815, a Cherry Stream, and a big number of other USB devices, such as mice (including two different Razer models), webcams, USB sticks all work as expected.
