The USBV2 and USBV3 jumpers are for the internal USB headers. 1. This feature requires a power supply that can provide at least 1A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up. 2. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
