I just got an WD15 to go with my existing Inspiron 7378. For the most part it works well. HDMI video, USB, and Ethernet all work as they should.
I can't get the firmware update to run on my machine, though. It says that no dock is detected. Additionally, there are about 4 "installing driver" dialogs that pop up when I connect the dock. They never finish. I did install the USB Audio and Ethernet drivers, and at least the Ethernet works like it should. So I don't think it's detecting those again.
If I can at least get the driver dialogs to go away then that would be a start. Since the dock works I'm less concerned about the firmware update, but would like to do that too, since it's listed as "Urgent"
I'm running Windows 10, and my notebook has a Core i7-7500 and 16GB of memory with a 256GB SSD. Thanks for any suggestions.
