Surface Book 3 - external keyboard and mouse

Anonymous

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.

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

    If you use bluetooth to play music, you probably has to keep the SB3 cover opened --- that is, making sure your SB3 screen is not shield by SB3 keyboard.

    [Update] Sorry. I didn't see you're using SB3 screen as the 3rd screen. Please ignore my comment.

    While definitely not a fix, I can confirm that I have been running Folding@Home in the background on my SB3 now for over a week, and the problem has not manifested itself a single time, as long as F@H is running.

    Keeping the CPU busy seems to prevent the low power state that appears to cause this fault.

    If I close down F@H and let the CPU enter a low power state as it normally would, the problem reliably reoccurs.

    So while we wait for MS to even acknowledge this as a problem, I can confirm that running F@H in the background on Low setting is a viable workaround to be able to use your machine as intended.

    Cheers.

    I tried this this today and can confirm that it has worked for me as well. Thank you.

    Not sure if it's related. I had hard time when typing with external keyboard (sometime it generated repeated characters or frozen for 2-3 secs). I moved my SB3 away from its dock and my keyboard went back to normal. Here is my setting:

    1. Only one SB3 USB port is used for wireless mouse.
    2. My wire keyboard is connected through dock.
    3. External monitor comes through dock as well. SB3 screen is off.
    4. SB3 cover is opened.
    5. Driver was updated a few days ago.
    6. SB3 is 50 cm higher and 30 cm away on dock's left side.

    I guess somehow my dock emits EM wave which interferes my USB signal on SB3. There is another trick seems working --- launching a small program to keep your CPU busy (see page 10 in another thread).
