3.USB Device Wake-Up (3x3 pin USBV1, USBV2, USBV3)

The default setting, [1-2] (+5V) disables the USB wake-up feature. Reset these jumpers to pins [2-3] (+5VSB) to wake up the computer using USB devices.

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. Also note that ONLY USB +5VSB can support S3 resume function.
