RE: XPS 9550 not working with TB15 Dock

New updates are available. Strangely enough, Dell update systemtray application does not see these updates and no mail notification from the Dell site. See

I installed them yesterday, no problems so far. When I talked to Dell technical support last month they advised installing updates in a certain order. Normally: BIOS, Drivers, Firmware and Application, but for the TB15 they advised installing the control driver _before_ the firmware. Given that the list of software seems to contain duplicates, my installation sequence:

I did not install the audio drivers at this moment, since I do not use those features. Will keep you posted if there are any problems. Hope Dell finally got this problem sorted out and it is not a hardware issue as some people imply.
