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.
