Mac Mini M2 Pro USB devices not recognized via monitor usb hub

I'm struggling with a strange problem, with a oled Philips Evnia 49M2C8900 connected to my Mac Mini M2 Pro. The monitor has a KVM functionality, so you can use 2 machine connected, one with video and data on 1 usbc cable, the other on HDMI or DP + a usb upstream cable usb3: the monitor also has 4 usb ports where I connected all my pheripherals, including mouse and keyboard. Let's focus on the usbc cable: when it's connected to my Dell working laptop all works as expected, full resolution, full refresh rate, all usb devices recognized. The same cable connected on a usb c port on my Mac Mini M2
