VDD5使用常电供电,VBUS供电使用ID PIN控制,当检测到有设备插入,ID PIN会输出低,此时再给VBUS供电。这种情况下是原先能识别的那一面不能识别了,原先不能识别的那一面能识别了(正好反了过来)。
yes, you need AC cap between hub downstream and USBC connector,

AC cap can be at input or output of MUX like HD3SS3220,
USB3 data rate is fixed either 5Gbs or 10Gbps, AC cap will affect the USB3 link working or not.
