3) USB Device Wake-up (2x3 pin USBPWR01, 23, 45)
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).
The USBPWR01 jumper activates the rear panel USB ports. The USBPWR23
jumper activates the internal header, USB23
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.
