3) USB Device Wake-up (USB01_PWR / USB23_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).
NOTE! 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. The total current consumed
must NOT exceed the power supply capability (+5VSB) whether under
normal working conditions or in sleep mode.
