I have the new style dock but the USB ports don’t work. I read that this could mean it needs a firmware update, so I downloaded the firmware updater tool. This shows that the firmware is indeed out of date, and begins the process of updating. However, after the process starts it immediately fails with the message “Firmware update failed. Please power cycle the Surface Dock and try again.” I have done all kinds of power cycling, including leaving it unplugged all night, tried flipping the plug on the PC over (read that in another forum :)), and have used three different Surface Pros to attempt the update – nothing works. Suggestions??
