I’m trying to disable wake up from suspend for all (USB) devices except the laptop’s own keyboard. Anyone did this?
I’m toggling settings in /proc/acpi like this (if enabled, checking with e.g. “cat /proc/acpi/wakeup | egrep -i pci | egrep XHC0 | awk '{print $3}”):
sudo sh -c “echo XHC0 > /proc/acpi/wakeup”
sudo sh -c “echo XHC1 > /proc/acpi/wakeup”
sudo sh -c “echo XHC2 > /proc/acpi/wakeup”
sudo sh -c “echo XHC3 > /proc/acpi/wakeup”
sudo sh -c “echo XHC4 > /proc/acpi/wakeup”
And to:
sudo sh -c “echo ‘enabled’ > /sys/bus/usb/devices/1-4.3/power/wakeup”
sudo sh -c “echo ‘enabled’ > /sys/bus/usb/devices/1-4.1/power/wakeup”
sudo sh -c “echo ‘enabled’ > /sys/bus/usb/devices/1-4/power/wakeup”
These are some external USB devices:
sudo sh -c “echo ‘disabled’ > /sys/bus/usb/devices/1-2.2.4.3.2/power/wakeup”
sudo sh -c “echo ‘disabled’ > /sys/bus/usb/devices/1-2.2.1/power/wakeup”
But it seems this is overly aggressive as it only allows the laptop’s power button to wake up from suspend not the keyboard. Anyone can help?
Thanks!
