RE: Dell XPS 15 9560 with Thunderbolt Dock TB16 doesn't see USB devices before restart

Jump to solution

Are you using Windows 10? I was having the same problem except it was affecting all my USB ports (laptop and dock) as soon as I first connected the TB16. The way I fixed it was go into device manager > Universal Serial Bus controllers > right click ASMedia USB Root Hub > Power Management > uncheck allow the computer to turn off this device to save power. I ended up unchecking it on every single USB device and also all the USB devices in the Human Interface Devices section and that fixed the problem but I believe ASMedia USB Root Hub was the one that fixed it for the TB16.
