Surface Dock keeps disconnecting/reconnecting USB devices with Surface Book 2

Hi 

I just bought a Surface Book 2 and a surface dock.

The dock is connected to 2 monitors and USB keyboard (Razer Huntsman Elite) and mouse Razer Hyperflux Mamba/Firefly.

Both keep disconnecting/reconnecting randomly. Mostly when running games, but sometimes also when running office application.

I have reinstalled the Surface Dock Firmware updater but it doesn't help.

I have done the latest updates, but it doesn't help either.

I cannot find much info in the event viewer, but SurfaceDockFwUpdate errors (event ID 2005 2006 and 2007).

Any ideas where this could come from?

This is becoming ridiculous, it sometimes disconnects every 5-10 sec.

    I have this too, it's driving me insane! My SP7 connects fine and stays stable, just my SB2.

    I am having the same problem with and without the dock.  I have a USB mouse plugged into SurfaceDock keyboard and it does it too.

    It still happens. Before I purchase the surface dock2, my logo g903h works just fine. But after I attach it to my surface dock2, the disconnection issue would happen about 10 min after using it. Update firmware doesn't resolve the issue.

    I solved my surface dock2 mouse disconnection problem. For me, it has something to do with my power supply: I plugged my surface dock2 into a power strip, which only provides 250w power while I also plugged in other equipments on that. Solved by plug my surface dock2 directly into a wall plug
