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 http://www.dell.com/support/home/us/en/19/product-support/product/xps-15-9550-laptop/drivers/advance...

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:

1. BIOS
Dell XPS 15 9550 A10 System BIOS
XPS_9550_1.2.10.exe
01.02.10 ,01.02.10 Release / Updated: 05 Jul 2016

2. Driver
Intel(R) Thunderbolt(TM) Controller Driver
Chipset_Driver_D91CC_WN32_16.1.47.275_A02.EXE

3. Driver - name double? Other file...

Docks_Stands_Driver_2VCD4_WN32_16.1.47.275_A02.EXE

4. Firmware - diconnect TB before install
Intel(R) Thunderbolt(TM) 3 Firmware Update
Intel_TBT3_FW_UPDATE_NVM16_A04_2.16.01.003.exe
2.16.01.003 ,A04 Release / updated 08 Jul 2016
    -> there is a duplicate entry; seems to be the same as the release / updated from 06 Jul 2016

5. Firmware - connect TB before install

7. Driver
Intel HD Graphics 530/P530 Driver
Video_Driver_FK4F6_WN32_20.19.15.4454_A06.EXE
20.19.15.4454 ,A06 Release / Updated: 29 Jun 2016

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.
