Thanks for the link. Interestingly Matthew Garrett says there that powertop is actually doing it in the wrong way (USB autosuspend), so maybe this is a bug in powertop (bug in the sense of using a wrong/old implementation)? As I said in my other reply, I've found out that my mouse can actually auto- suspend successfully (and wake up) by modifying /sys/bus/usb/devices/.../power/ausotsuspend (while powertop kills it altogether). So maybe that's the one that powertop should touch when you press the U key? > > > - jan _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
