I am trying to follow the instructions on Lesswatts, to enable usb autosuspend.
When I run
powertop, it says, that I have a device (USB device 2-6 : 2.4G Multimedia Wireless Kit (Chicony)) that is running 100% of the time.
I don't use the wifi and indeed I've blacklisted the wifi driver, so I am pretty confident I don't need this device. So I set the idle timeout to 2 seconds and
echo auto >
works, but the device is still active. If I try
echo suspend >
then the bash prompt skips ten lines and stops, but the contents of the file is still auto
