The only solution currently that brings the devices into a functional state is to reduce the mouse DPI.

There is a big issue in the recent firmware/driver update pushed to the surface book 2. The usb mouse became not really usable. There is a frequent lag/freeze happened to the mouse. Such issue was not there before the firmware update.
The mouse I tried including Logitech G703, G402, microsoft wireless mouse, etc.
Many people have discussed this now but not solution is provided and the problem cannot be solved now:

A further test can now confirm that the issue is either in the UEFI version 389.2268.769.0 or the system aggregator version 728.128.137.0.
After updated these two modules to those versions, the issue start to appear. This has been confirmed on more than one surface book 2 devices.
The previous version of the UEFI starting from 388 and aggregator version 728.77.137.0 do not have such issue. I can see at the moment, the 389 version of UEFI is not pushed anymore and the firmware/driver pack downloaded from Microsoft has the 388 version now.
But for those surface book 2 which has already got the 389 version pushed cannot revert back to the 388 version. Please fix this asap.

2019-11-13T23:50:12+00:00 Hey @skytulip33, I'm curious if you have tried to update one of the affected SB2s under your care to the latest firmware updates released October 11, to see if it addresses this problem?
Since it is impossible to downgrade UEFI after an upgrade (and also likely impossible to downgrade other firmware components in the machine as well, such as "system aggregator"), I have actively worked to prevent my SB2, which still has UEFI 388.x.x.x, from updating itself. It would be a relief to no longer have to worry about needing to police this out of fear that I'd have to permanently live with this regression.
Also, can anybody shed some light on why some SB2s have System Aggregator firmware versioned with a numbering scheme of 182.x.x (like mine), and others are 728.x.x? It doesn't appear to be a 13.5" vs. 15" thing, since there are 13.5" units out there with 728.x.x firmware...is it a dGPU-base vs. non-dGPU-base thing? The weird part is that the Surface Book 2 Update History (changelogs) never mention the 728.x.x SysAg, just the 182.x.x one.

2019-09-01T06:51:08+00:00 This issue still exists on my PC. Limiting it to 3.8 GHz didn't work... Any other ideas? This is a very frustrating issue. Makes it impossible to use my mouse.
