This ensures that the device can boot from a USB device prior to MMC. Useful cases are when installing a new OS from USB while MMC still has a working OS configuration or if the OS configuration is broken in late boot stages (kernel boots but the system does not start).

What's the implication of this if no USB mass storage device is found? How does this behave when USB cannot be read or booting from it doesn't work?

I vaguely recall that boot order doesn't always proceed, though admittedly I haven't tested all of these edge-cases in a long time.
