No USB Power (ROCK64+ARMBIAN 5.7) - takezo - 03-15-2019

Hello, can someone help me with my problem.
I have a ROCK64 with 4GB of RAM and an ARMBIAN 5.75 stable Ubuntu 18.04.2 LTS 4.4.174-rockchip64, installed.
My issue come with usb ports, from the three USB of the this device only works two: one 2.0 and 3.0. And when i have a disk connected towards usb 3.0 i have issues with port usb 2.0, it doesn't work well and I end up disconnecting the USB 3.0 to can work with my device connected towards USB 2.0 so I assume that the current power on the USB port is having issues or it's not working well.
Anybody an idea?
thanks!

Typical power supply issues. You can either try a different power supply to rule this in or out or use a meter to measure the current draw on the power supply when all USB ports are in use.
