USB Power Select
Jumper JPUSB is used to select the
power state for the USB ports. The
Standard setting means power is ap-
plied to the ports only when the system
is powered on. The Dual Power setting
will allow the USB ports to have power
whenever the system's AC power cord
is connected, regardless of whether the
system is powered on or not. See the
table on right for jumper settings.
