Hi all I have UART connected to my MiBox S (which doesn't have a SD card slot only 1 usb).  I'm trying to see if it can boot from USB, but it says there are no storage devices connected.  Is it possible or am i just wasting my time:

No storage devices, perhaps not 'usb start'ed..?

I figured it out, basically there is zero power going to the USB port, so i had to use a usb splitter cable and a hub.
