I have just started trying to use a BPI-M2 PRO and have noticed a problem regarding the what I believe to be USB WiFi (the RTL8821CU is supposed to be USB). The USB does not appear to recognize the RTL8821CU at all. Below is the output of lsusb -t without anything in the 3 USB ports.
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
As you can see there is no WiFi modules showing. Below is the output with a USB device in each of the 3 USB ports.

Do I have a defective board? Or is there something I need to do to get the WiFi to be recognized?
