U4025QW, USB hub issues

U4025QW in USB KVM mode. TB4 connected to MacBook M1 Pro. DP + USB-C connected to PC. USB hub connected to daisy chain USB-C / TB4 port. Also tried USB hub connected to regular USB-A port. 

If connected to the daisy chain port: USB hub devices only work on Mac (TB4).

If connected to a USB-A port: USB hub devices only work on PC (USB-C).

Some users are likely to want to use a USB hub device, as wiring can result in high clutter. Port count can be insufficient in some cases, such as in mine. I had no issues with U4021QW with this configuration.
