The problem is only with the USB port. I'm using an USB power meter to 
discard a problem in the communication with the USB devices. It has a 
LED which only requires GND and +5V to work. So, the firmware is not 
enabling the USB ports. U-boot boots fine but the USB doesn't even 
receive power.

Armbian is using 2018.05 and with their version of u-boot, the USB works 
fine. IIRC, a year ago I was using the same version of u-boot with 
OpenBSD and an USB HDD connected without problems.

U-boot complains because there is not a partition on the SD card but the 
USB receives power.
