P2418HT, USB extender, Touch working on one
I got two P2418HT connected to one USB extender. Somehow, the built-in USB hub only works in one of those monitors. So, touch function also works only on one of those. And I can see only one HID compliant touch screen in the Device Manager. If I connect only one monitor to the extender, than it works ok, no matter which monitor I connect. So it's not an issue of touch, or built-in USB hub.
If I connect second monitor to the left side USB port of the first monitor, it doesn't work too. So daisy chaining USB doesn't work as well.
If I get another USB extender and connect each of the monitors to their respective USB extender, then everything is ok, I can see two HID-compliant touch screen devices in the Device Manager.
So, is there any way to make two P2418HT monitors share one USB extender?

The P2418HT never supported daisy chaining.
Monitor daisy chaining only works if the 1st monitor has either a USB-C video port or the DP out port to connect to the 2nd monitor DP in port.
Each of the P2418HT #6 USB-B upstream ports (P2418HT User's Guide, page 9) must each be connected to the USB extender via the provided USB-B to USB-A cables (page 6).

I have never seen any Dell monitor documentation that states if that is possible.
