Hi,

As the subject line says, powertop constantly tells me my USB devices
(keyboard/mouse) are active 100% of the time and to enable USB
suspend, which I do, but it keeps telling me constantly. How can I
tell if:

A) USB suspend is actually on or not
B) powertop is doing anything when I press "U"

I've got USB Suspend/resume support in my kernel, and according to the
kernel docs the usbcore.usbsuspend default delay is 2 (powertop
suggests changing it to 1).

Powertop's refresh delay is 5 seconds.

Thanks,
Paul
