RE: Dell TB15 Desktop Dock - Step-by-step driver/firmware/BIOS installation instructions for XPS, Latitude and Precision notebooks
I have followed all the instructions for the TB15 with a XPS 13 9350 (Win10 64-bit) and I get disconnects on USB mouse and keyboard still. The disconnects happen every 60-90 seconds. I have tried all the USB ports with multiple keyboards and mice that work fine when plugged directly into the laptop.
USB thumb drives seem to work fine though. I was able to transfer files to and from several thumb drives without interruption.
Ethernet seem to be working just fine.
HDMI and Displayport seem to be working fine. I have yet to try the mini-displayport and vga.
