I recently got the TB15 dock with the 180W power supply and there seems to be a lot of issues USB connectivity and some other minor issues when used with a XPS 13 9350.
I have noticed the following:
Before using the dock I had made sure to :
Video, Ethernet and Power of the TB3 connection to the laptop all seem to work fine. As a work around (hopefully temporary), I am using a USB 3.0 hub plugged directly into the laptop so I can use a mouse and keyboard while docked.
Any help in this matter would be greatly appreciated.
I'm beginning to think there is a fault in the TB15 180w. With all the latest patches (as of today) the device would randomly disconnect all attached devices including two 1080p monitors (one HDMI, one DP), mouse, keyboard and internet. The whole time including during the disconnections the Intel Thunderbolt app is still saying the cable and dock are connected.
When feeling the case the TB15 is running very warm. Everything I tried gave me the same results.
Until that is, I unplugged my HDMI cable and plugged it directly into my laptop (XPS 15 9550). Within minutes the TB15's case temperature dropped and is now stable. I'm beginning to think the TB15s are overheating and crashing.
Dell, why is there no venting on the case?!!

We have just bought 2 XPS 15 9550 with TB15 docks and having exactly the same issues.
Have all the latest drivers installed including the latest firmware. Pretty much makes this dock useless.
