P2721Q, USB-C to USB-C upstream to Lenovo X1, SuperSpeed ports don't see devices
The monitor works fine. The USB 2.0 downstream ports see the keyboard and mouse to which they are connected. But the SuperSpeed ports don't see the disk drive that I've connected to them. The Lenovo sees it fine when it and the disk drive are connected directly.
I'd be grateful for any help/advice.

Was that P2721Q purchased directly from Dell?
Check the P2721Q warranty by inserting the private P2721Q Service Tag here.
What is the build date and revision on that P2721Q? Check the rear label.
What firmware version? Check the Menu- Others. The only firmware on the P2721Q Drivers & Downloads page is M3F103.
The P2721Q USB-C only delivers 65W back to the laptop. Is the Lenovo supplied power adapter connected to the Lenovo X1? If not, do so and retest.
List every port on the Lenovo X1.
