1.8.1.3 Watchdog timer output (JWDT1)
The ASMB-585 contains a watchdog timer that will reset the CPU. This feature
means the ASMB-585 will recover from a software failure or an EMI problem. The
JWDT1 jumper settings control the outcome of what the computer will do in the event
the watchdog timer is tripped.

1.8.1.4 USB power switch (JUSB1/JUSB2)
The ASMB-585 contains a jumper that can support on board USB ports power source
from +5Vsb or +5V. The JUSB1 jumper controls the USB2.0 and 3.0 ports of rear
window. The JUSB2 jumper controls the USB2.0 and 3.0 ports of onboard header
and connectors. The default setting is 1-2 closed which is supports USB stand-by
power under S5. When the jumper is 2-3 closed, the on board USB ports power
source will be switched 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.
