Laptop unable to see TB3 device when plugged into TB16 240w dock
I have a Dell XPS 15 9560 laptop that I've updated with the latest BIOS and drivers. I also have a Dell TB16 240w dock. I recently bought a Sonnet Echo Express SE1 TB3-PCIe Chassis where I've installed a 10Gbit Ethernet card. When I plug the Sonnet Chassis directly into the laptop, the laptop sees the network adapter perfectly, but if I plug the dock into the laptop and the Sonnet into the dock, it fails to see it (the network card). Any ideas??
I can plug the Sonnet chassis into my laptop and plug the dock into that, but then I lose the ability to charge my laptop via the TB3 cable. Not ideal.

Interesting, I would have bet that would work. Check the settings area of the Thunderbolt Software application and see if the option to ignore the “first device in the chain” restriction is enabled. If the Sonnet enclosure requires that it be the first device, that option may allow it to work even when it isn’t, or it may still not work. I would be surprised if that enclosure had that requirement, though. Any chance they have a useful support team you could ask about that?
