HP Thunderbolt Dock G2 120W with non-thunderbolt host Lenovo ThinkPad X260
Product: HP Thunderbolt Dock G2 120W
Hi All, I've got the Thunderbolt dock running latest firmware and a Lenovo ThinkPad X260 laptop. The x260 has 3 x USB 3.0 Type-A ports. The HP Thunderbolt Dock G2 Specifications page says the dock with work with non-thunderbolt hosts. Obviously I don't expect the laptop to get power from the dock which is why I have the laptop plugged in.
I've got a USB Type-A to Type-C cable. the Type-A jack is plugged into the laptop. The Type-C jack is plugged into the open Type-C port on the dock.
The laptop will not work with the dock in this configuration. I also tried a Lenovo ThinkPad T560 laptop and that did not work either.
How can I get this laptop (or any non-thunderbolt host with USB 3.0) to work with the dock?
