Surface Book i7 512 (just opened yesterday). A plethora of issues and I'm on my second dock with no resolution! Connecting anything USB is mostly broken. I cannot connect even something simple like a USB mouse or keyboard; the Book doesn't beep; it's like it isn't detecting the connections. DisplayPort - if I connect to it then the Book's monitor goes black and flashes. I'm using the same connection I used for my Surface Pro 2; I moved the connections one to the other. I went to the company store and tested the surface with a dock they had on the display and the mouse was found and DisplayPort worked (but that was the dock on the display). They exchanged my dock and I tested at the store; same issues, mouse wouldn't come alive. Just to verify the Surface Book; I connected it to the display dock and the DisplayPort and mouse worked so I figure the Surface Book is likely good. Since I can't imagine 2 out of box failures I left with the replacement dock and it's pretty much a power brick at this point (oh, the network connection works). I've done all updates and everything else I can think of. Any ideas? Is it possible I have a second bad dock?
