Hi All - I just got a TB16 to replace my old USB3 dock that had dead USB ports on it. I have followed the information in the TB16 setup guide, the driver installation guide and tried a lot of different things. The TB Controller is enabled and security is disabled in BIOS. I also turned on all the checkbox options in BIOS, and have toggled them on and off to make sure they are actually turned on.
None of the USB ports on the new TB16 work, the sound ports do not work, and the NIC does not work. I am able to get the display ports working (using both right now, connected to USB powered Dual-Link DVI adapters connected to my good old 3007WFPs).
I have tried several "down rev" versions of the USB controller driver that is provided by Dell. I cannot even see any evidence of USB devices when the TB16 is connected with the 240W power adapter connected. However, if I unplug the 240W power adapter from the TB16, I do see some USB devices pop up, but they don't work. I have tried leaving the dock disconnected from everything for 4 days and then connecting the power adapter to it, then connecting the laptop. That did no good either.
I also tried using the recommended "disable WiFi" fix that was posted here in the forums. That made no difference. It makes no difference if the laptop is off and powered up with the lid closed or with the lid open. I also cannot use a USB keyboard connected to the TB16 on the bitlocker prompt screen, regardless what port it is connected to.
I'm starting to think this thing was DOA. Please help.
