No Problem, So I been testing the PT-PTC-D-AF and eth/PD hubs also, and what i able to find out is that is that the USB-C cable can cause it not to work,
G3I: USB-c are hit or miss, some of them worked, only did power, G3I i got in 2021, my last 2 in 2022 the usb-c cable worked just fine
USB-C 3.X cable work the best for me for both the HUB and PT-PTC-D-AF
G4I: it just worked for me
Links to the hub: will get gigabit
