5. USB Device Wake-Up (2x3 pin USBPWR_12, 34)
The default setting, [1-2] (+5V) enables the USB wake-up feature. Reset
these jumpers to pins [2-3] (+5VSB) to disable the wake up feature.
The USB device wake-up feature requires a power supply that can
provide at least 1A on the +5VSB lead. If this requirement is not met,
the system does not power up. The total current consumed must NOT
exceed the power supply capability (+5VSB) whether under normal
condition or in sleep mode.
