Public bug reported:
Binary package hint: powertop
When running powertop, it suggest adding the usbcore.autosuspend=1 to
grub's kernel line to turn on usb autosuspend powermanagement.
Unfortunately, when booting you get this error message:
unknown boot option : usbcore.autosuspend=1 ignoring
I have read somewhere that this autosuspend should be added to
/etc/sysfs.conf after installing sysfsutils
module/usbcore/parameters/autosuspend = 1
but i'm not sure that works.
