I guess the repeater doesn't really check the vendor of the PHY, i.e. if someone took a SMB2360 and hooked it up to any other eUSB signal, it would happily crunch through them.. That said, I'm just spitting out words and this is probably good to inform the user about the actual real-world usage Reviewed-by: Konrad Dybcio Konrad
