Good idea, but this is not connected via USB (`lsusb` doesn't show
anything related to mouses or keyboards). It's the mouse button of my
Thinkpad's trackpoint, which AFAICT is connected "internally". My web
searches suggest this uses the old i8042 PS/2 controller.
But I can't see any power management in there:
# find /sys/module/i8042/
/sys/module/i8042/
/sys/module/i8042/uevent
/sys/module/i8042/parameters
/sys/module/i8042/parameters/unmask_kbd_data
/sys/module/i8042/parameters/debug
#
Any idea how I could control the power saving (or even if there is any
power saving to control) in there?
