10) USB Device Wake-up (USB01_PWR/USB23_PWR/USB45_PWR)
Set these jumpers to +5V to allow wake up from the S1 sleep state (CPU stopped;
RAM refreshed; system running in low power mode) using the connected USB
devices. Set to +5VSB to allow wake up from S3 sleep state (no power to CPU;
RAM in slow refresh; power supply in reduced power mode). The default setting
for the three jumpers is 1-2 to select +5V (because not all computers have the
appropriate power supply).
NOTES:
1. This feature requires an ATX power supply that can supply at least 2A 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 working conditions or in sleep mode.
