Is it a good idea to extend the USB 3.0 (for power supply) port instead of the USB 2.0 port?
This port is using normal USB3.0 (not PowerDelivery) for powering purposes, so it needs to power exactly 5V-3A with bus power, and in some tests the transfer quality is also poor.
However, the bandwidth is much larger than the 2.0 port, so I plan to test some hubs and injectors.
Since it not officially supported originally, I think that there is not much difference between OpenWrt and Ubuntu.
