Hi Everyone,
Thank you for sharing your feedback and questions with the community. I'm hoping you can help me gather more information relating to Windows detecting/not detecting ("bouncing") USB devices plugged into the Surface Dock.
I am looking for details on the types of USB devices connected to the Surface Dock. If known, please include the USB standard (2.0/3.0) for the connected USB devices.
Thanks,
Josh
Pictured below:
- Logitech Performance MX mouse unified wireless dongle (USB 2.0)
- Acer T232HL 1080p Touchscreen Monitor (USB 3.0)
- This monitor is also connected to the dock using a passive miniDisplayPort to single-link DVI. It has a 3 port USB3.0 hub built in, but I don't use it (as you can see in the picture)... I only have to plug its USB cable in so I can use the built-in touchscreen.
- As for non-USB... I also have a Dell P2715Q (DP4k60) 4k monitor plugged into the other mini display port, and I use the dock's gigabit Ethernet and headphone jack... both of which also bounce.
I'm certain there is no problem with any of these devices as I used both of them (and the 4k Dell monitor too) with my Surface Pro 3 and Surface Pro 3 Dock without any issues throughout the pre-launch Windows 10 preview, prior to "upgrading" to this expensive
(512GB/i7/16GB/dGPU) frustration inducing Surface Book. I only wish I hadn't sold them.
If you want to try to avoid the problem, I've found that shutting down completely, then plugging in the dock, then booting up will usually (though not always) lead to the Dock's USB functioning for a few hours (or until the Surface Book sleeps, or the dock
gets disconnected, or the display gets detached from the base). Usually, not always.
If you're looking to reproduce the problem, simply plug the dock into the Surface Book while the Surface Book is already on. It'll start bouncing (and eventually fail completely) in no time. Also a sure shot: disconnect the display from the keyboard base.
Holy cow does the Surface Book hate that. Not only with USB devices stop working, your keyboard and trackpad will cut in and out too. And the device will forget it's plugged into power at all and won't take a charge.
And this isn't some fluke... I've swapped out (individually) both the dock and the surface book twice. I also tested with the display model in the Microsoft Store and it did the same thing. So the failure rate for me is 100%. I've heard some say they don't
have problems. I have a hard time believing those people use the dock or ever unplug from power, or ever disconnect the screen.
Here are pics of the devices:
