usb wakeup control

usb-wakeup-control

This simple utility enables or prevents specific USB devices from waking up the system upon suspend. Pretty useful if your Linux laptop or PC refuses to go to sleep because some USB device (like my Logitech G915 wireless keyboard receiver) is keeping it awake. Also useful to prevent unintended mouse movements from accidentally waking up your laptop.

Usage

Command	Description
./usb-wakeup-control.sh install	install this script as /usr/local/bin/usb-wakeup-control and add a systemd service to /etc/systemd/system. NOTE: This is required for the other commands to persist after rebooting or unplugging and replugging.
./usb-wakeup-control.sh detect	list all connected USB devices and their current wakeup status
./usb-wakeup-control.sh disable vendorId productId	disable wakeup for a specific USB device
./usb-wakeup-control.sh enable vendorId productId	enable wakeup for a specific USB device

Vendor ID and product ID can either be found using usb-wakeup-control detect or lsusb.

For example, if lsusb shows:

Bus 001 Device 007: ID 046d:c52b Logitech, Inc. Unifying Receiver

then the vendor ID is 046d and the product ID is c52b.

The disable and enable commands will store the given USB device vendor ID and product ID in /etc/usb-wakeup-control/disabled or /etc/usb-wakeup-control/enabled, respectively, to ensure persistance after rebooting or unplugging and replugging. You could create these files manually, but it's recommended to use the disable and enable commands to ensure the correct format.

Examples

• usb-wakeup-control detect
• usb-wakeup-control disable 046d c52b
• usb-wakeup-control enable 046d c52b

Note: disable and enable require sudo (root privileges) to write to /sys/bus/usb/devices/*/power/wakeup
install also requires root privileges to write to /usr/local/bin and /etc/systemd/system
