[gentoo-user] Powertop constantly tells me to enable USB suspend, but it is already enabled
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
