A fix for this issue is now available through Windows Update. Please review the Surface Book 3 Update History page.

I have a SB3 connected to a Surface Dock which has FullHD touch monitor, USB keyboard and mouse connected to it. I have used this setup without any issues for over 2 years with Surface Laptop 1.
With the SB3 the keyboard and mouse 'stutter' meaning characters are lost or autorepeat due to missing down or up codes. Mouse motion ceases then resumes.
I have a video of the mouse re I continuously move the mouse in a circle

I have tried plugging the mouse into one of the SB3 USB ports and get the same result.
I know others have seen this problem. It should be easy to reproduce. Can someone from Microsoft try this please.
This looks to be a level USB message handling problem. Note that the USB is not unloading.

That said, Bluetooth Keyboard and mouse 'appear' to fix the problem.

Also, is the problem limited to the mouse and keyboard or are other USB connected devices like hard drives affected?

After testing, I can confirm that none of these updates resolve the issue.
