I think it was just a few sysctl calls I found on the FreeBSD wiki to

What exactly do you do to accomplish that?

Hello,
I've looked into *usb/controller/usb_controller.c* and modified
usb_bus_suspend():
==
*Line480*
// * We use the shutdown event here because the suspend and
// * resume events are reserved for the USB port suspend
I am VERY new to this but was just doing some hacking on my laptop
(zenbook) and found if I poweroff my USBs (while the rest of the machine
is still being used) I gain an hour of battery life.

Hi,
I'm not sure. You'll have to find out. It is what happens when you
suspend which decides if you get the resume event or not. Once

So, is the BIOS handover to the USB stack a prerequisite when resuming from
standby mode HC (not completely off HC)?
In other words, do we need to implement BIOS handover before we can use
wake on usb keyboard input?
Or is there a workaround for this specific functionality?
Many Thanks aga
