$0: a script that lists and toggles wakeup on usb hubs
Usage: $0 [options] [action] [parameters]
Actions:
-l : list available usb hubs/devices that can be toggled and their
current status (enabled/disabled)
-a : enable wakeup on all discovered usb hubs/devices
Use caution with this; it's better to identify individual
hubs/devices rather than enable them all. You might find
your computer woke itself unintentionally.
-x : disable wakeup on all discovered usb hubs/devices
-e : enable wakeup on specific hub/device (requires parameter,
see below.)
-d : disable wakeup on specific hub/device (requires parameter,
see below.)
-h : this screen
Options:
-q : Quiet mode for all but help and list actions
-v : Enable verbose output
-k : Try to show hints from dmesg (list action only)
This dmesg option will show lines starting with input
in order to try to identify devices.
It is usually presented as /sys/devices/*/usb?/*/input/input?.
If nothing useful is displayed, try rebooting as relevant
information can be out of the buffer if the PC has been on for
some time.
Parameters:
Both -e and -d actions require a parameter to search for, use -l to list.
The parameter needed is in the Device column.
Sample output of $0 -l:
Listing USB devices and their wakeup status...
USB ID :: Device* :: Status :: Device Description
----------------------------------------------------
1d6b:0001 :: usb4 :: enabled :: UHCI Host Controller
046d:c508 :: 4-1 :: enabled :: USB Receiver
046d:c221 :: 4-2.1 :: enabled :: Gaming Keyboard
The identifier needed for the parameter is usb4, 4-1, or 4-2.1.
No arguments will show this screen.
