Actually - I did all those (latest updates as of Feb 02) and it didn't. I have already returned it to Dell and now the docks are off their website (both 240W and 180W). Many people on Notebook Review forum had the same issues with all latest drivers but someone applied the latest USB drivers from ASUS and it started working again.
Any idea when Dell will re-release the Docks (in working condition)?
Upgrade Bios, upgrade TB firmware and install ASmedia USB controller driver version 220.127.116.11. Dell doesn't provide this driver for unknown reasons, you can grab it from another manufacturer that provides drivers for the hardware they sell, like Asus:
Under USB. Everything will work just fine.
Can someone please provide me with the URL of the TB15 on the US site? I would like to have my company buy one for me and I need a URL to provide them.
The device that's having issues is the ASMedia 1142 USB controller.
There's a good post on reddit about how to install new drivers for the USB controller--appears to be working:
Thanks for getting back to me. Updated the BIOS and new Thunderbolt drivers. Do you have a list of the exact Thunderbolt drivers I need to have installed? I noticed there are some Thunderbolt drivers posted for the WD15 that didn't show up in my XPS driver list. I installed the applicable Thunderbolt drivers from there as well. It would be helpful if there was a way to cross reference the drivers I have vs. what you post so I can see if I'm missing one.
Is there a certain order these have to be installed in?
The USB ports seem to simply be unstable. My USB speakers cut in/out. USB Logitech wireless mouse cuts in/out. Hope you have a fix!
Now I only have one nagging problem left: the excessive fan noise when the USB-C/TB port is in use. Even when the system is idle (and cold at ~30C), fans are constantly spinning.
Could someone @Dell confirm that this is a bug and it will be addressed in the upcoming A05 BIOS?
With the current bios version, and the 3 4 firmware/drivers/patches applied, the dock still does not work on my 9550.
Has anyone also had the following issues with the Thunderbolt 3 dock?
-When undocking from the Thunderbolt 3 connector my XPS 13's curser speed drastically slows down. It isn't until I do a restart that it returns back to normal. When docked and Logitec wireless mouse is connected directly there are no issues with curser speed.
-USB speakers and USB mouse/keyboard cut in/out when connected directly to the dock. Currently requiring me to plug directly into the laptop.
