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

My keyboard and mouse are both wired so unfortunately that won't help me. Hopefully it will help others. But my guts tell me that the culprit is the dock itself. Especially since dock 2 seems to solve the problem.

My reply on that post might be useful for some of you as I fixed my issue with Surface Dock 1 / 2 which only have USB 3.0 on it:

Surface Dock2 causing issues with Wireless Logitech keyboard and mouse - Microsoft Community

It's related to the USB 3.0 interference and USB wireless dongle.

I guess it's the main reason all keyboard / mouse (especially using wireless 2.4Ghz) are using USB 2.0 instead of 3.0

Just thought I would add my experience. In my case, it is definitely the Surface Book 3, not the dock.

I have the USB disconnect issues intermittently on the SB3, using two Dock v1, and one Dock v2. But I never have USB disconnect with SB2 on same three docks.

I have two external monitors, and they work fine with the SB2 with both dock v1, and Dock v2. The two monitors always work with the SB3 if I plug the dock into the bottom of the SB3 when it is disconnected from the base (tablet mode), or if the SB3 is connected to the keyboard base in laptop orientation where you can use keyboard and look at screen. But, if I dock the screen reversed, keyboard behind, then only one of my external monitors will work. The other monitor very occasionally will work in this mode, if I keep disconnecting and reconnecting enough times, but will then be disconnected the next morning.

Reinstalling Nvidia and Intel USB hub drivers did not solve the problem since they were already up to date for me. Simply reinstalling them made no difference. 

What made things a bit better for me is to go to Device Manager -> USB controllers and find all the "Generic USB Hub devices"

For each of those devices, you want to check and see that on their "Details" page they have the hardware ID as VID = 045E (Microsoft) and PID =0901, 0902, etc... to make sure they are one of the USB hub ports on the Surface Dock.

For each of these devices, I went to their Power Management tab and unchecked the box that says "Allow the computer to turn off this device to save power".

This seems to help because now I have fewer disconnections, but doesn't solve the problem entirely. I might have missed a root device or something else. 

The reason I'm looking in this area is because I noticed that the times when I'm seeing USB disconnecting seems to be when my Surface device is really stressed on performance, mostly when playing some games that has the CPU and GPU running near their limits, fan's going full blast and the computer's still getting warmer. It seems like when the system is thermal throttling, it decides to turn off power to the USB devices and disconnect your keyboard and mouse because as a side effect? What the hell. 

From this observation, I don't think spending money to buying a Surface Dock 2 would actually solve the problem if my suspicion is right -- this is a software configuration issue, not a hardware defect. Windows device drivers are being overly aggressive in trying to manage power and turned off devices that is detrimental to the user's experience. 

I advise everybody with this problem to experiment with the "Allow the computer to turn off this device to save power", particularly on the "Intel(R) USB 3.0 eXtensible-Hostcontroller". I use a different dock (Dell USB-C display) and had very very similar problems and it was this setting that fixed it for me. Try that before you get new hardware.

I bought my SB2 last year for $3k. Unless Microsoft is replacing it with an SB3 for free, I would never go back to MS laptops. 

Indeed what you're proposing is not a solution. And sounds like a MS speech. Won't work for me. 

This issue is also happening on surface pro device, so you're suggestion is to replace a $1000 device with a $3000 one. That won't fly for me.
