The ASMB-586 contains a jumper that can support on board USB ports power source
from +5Vsb or +5V. The JUSB1 jumper controls the USB3.1 Gen2 ports of rear. The
JUSB2 jumper controls the USB2.0 and 3.1 Gen1 ports of onboard header and con-
nectors. The default setting is 1-2 closed which supports USB stand-by power under

to +5V. If you want to disable USB stand-by power under S5, and under 2-3 closed, it
won't support S3 and S4 modes.
