Motherboard Settings

4) USB Device Wake-up (USBPWR)

Set these jumpers to disable or enable the USB device wake-up function. Set

this jumper to Enable to use the USB devices to wake up the PC. This feature

requires an ATX 12V power supply that supplies at least 2A on the +5VSB lead.

The default setting is Disable because not all computers have the appropriate

ATX power supply. The computer will not power ON if the jumper is set to

Enable without the correct power source.

NOTES:

1. This jumper must be set in conjunction with Wake On USB Device in BIOS,

4.5.1 Power Up Control.

2. To support wake up from USB devices, this jumper must be set to Enable.

2. The total current consumed must NOT exceed the power supply capability

(+5VSB) whether under normal working conditions or in sleep mode.
