Don't load usb if using suspend/resume.

/etc/defaults/rc.conf:
performance_cx_lowest="HIGH"            # Online CPU idle state
performance_throttle_state="HIGH"       # Online throttling state
economy_cx_lowest="LOW"                 # Offline CPU idle state
economy_throttle_state="HIGH"           # Offline throttling state

You could make your system run cooler while on AC power with:
echo 'performance_cx_lowest="LOW"' >> /etc/rc.conf

You can also use literal values, i.e. "C3"
