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

I just started having the same issue. I reboot and usually it goes away for a few hours or a day, then comes back.  I don't think it is the surface doc as i have a surface charger for my SB2 15" and it still drops my hard drive (USB) on occasion over and over.  The problem is it thinks the tablet detaches and re-attaches over and over.  I cleaned the connecters and it went away, then happened again today.  I think in many cases the issue is the tablet quickly losing connectivity with the base, dropping the doc and base USBs then reconnecting. 

Searching on this problem, it can happen when the CPU spikes apparently.

So I got the new Surface Dock 2: few surprises (good and bad).

1. monitor connections are now only using USB-C, so I had to purchase USB-C to HDMI cables
2. only 2 USB3 connections on the dock, my mouse and keyboard take 3 USB3, so I had to buy a USB3 to USB-C adapter

3) monitors are not working properly (one stays black, the other one displays whenever it wants)

4. the only short tests I could do regarding USB disconnection are good, as I don't have anymore disconnection.

Technically my problem is solved, but since my monitors are not working anymore, I guess this is not OK.

I have called the MS support, they're exchanging the dock 2, so I'll make a new update in few weeks, when I'll get the new one.

To be continued...

Would have thought MS should get their display issues sorted out with Dock 2, alas!

Amazing! I wonder if someone from MS is reading this. I used to be an MS employee, and in my days, this kind of disaster was paid with the job. I guess that the old Steve Ballmer "mantra" is still there:  "if your business unit is making more than 1 billion, then you are in a serious business". Guess what... all the money and priorities go there regardless of how strategic it can be for the future. Surface is not a serious business, so no serious effort is behind it as it has been for a very long list of products and services...

i think i found what the problem is. The MS dock power supply simply does not provide enough power (90 W), it produces even less than the original Surface Book 2 power suppy (95 W for the Surface, 102 W including the USB).

To resolve the issue right now you have 3 practical options:

1. do not use your Surface Book 2, connected to the Surface Dock, in "best performance", but rather find the performance-power equilibrium that best adapt to your particular situation; i would begin by "best battery life" and try for some time and increase it a bit until it start to disconnect intermittently again.
2. Get the new Surface Dock 2. It's being announced with a 199 W power supply.
3. Get a more powerful power supply that fits in the dock.

as you read above there is no software update, configuration (other than power consumption), replacement, or other that will let you enjoy your dock and Surface Book together to the fullest

This is complete tosh, it has nothing to do with the microsoft dock what so ever.

I am currently sat here with the power supply that came with the laptop, plugged in directly to the laptop. But the external monitor I use which has a built in USB-C/TB3 hub suffers from the same issue everyone here is describing. I can go for 2 hours with no issues then for no apparent reason what so ever I am finding USB devices lose connections.

If you open device manager and just watch it, you will see it keeps changing as devices are lost/re-appear. It's like it is automagically "scans for new hardware". I can sit here for 30 minutes while it keep repeating itself. 

I sometimes even find that when I'm just using the laptop with no external devices, I can even lose my geforce graphics card, like it was taken out of the machine and no longer appears in device manager unless I scan for new hardware again.

It's just MS trash to be honest. It is by far the most unproductive system I've ever had to suffer with and is exactly why our organisation will never buy into Microsoft hardware again because we are losing money every day dealing with these problems across our entire work force.

I totally agree, buy something else!

This is a Surface issue not a dock issue.

I had the same problem in the first couple of weeks (in this chain somehwere), and i have used different dock type devices on my Surface 3 laptop, and had the same issue.

I contacted MS, and they requested that i return it for a replacement. That was on 24th April, and i am still waiting for the replacement, aparently they dont have stock of my model!!

I have chased and chased and chased, and when you eventually get to speak to someone, no one cares or wants to resolve the issue. No offer of replacement upgrade or refund! They have now had it twice as long as i have owned it before it went back.

I contacted the complaints department, and guess what no response to that either!

£1500 wasted.

Disgraceful service!

My advice would be buy anything but MS!!
