Note - There are 3 USB ports on the motherboard, all of which are active at the same time (thus no need for a USB selection jumper). Two of the USB ports (USB 1 & 2) are on the back panel, two USB headers are on the board (USB 3 & 4). Only one of these USB headers (3) is currently populated. The jumpers J7 and J8 are used to activate Wake up from S3 state (one of the ACPI sleep modes)via a USB device (keyboard, mouse...) connected to one of the USB ports/headers.
