    Hi everyone,

    Running Armbian and I have two Edimax 7811Un wifi adapters plugged into the board. The one in the USB 2.0 port (rear left) works fine. The one in the USB 3.0 port (rear right) always gives error -110 (insufficient power) during bootup. The device is not recognized (lsusb).

    Anyone know how to fix this?
