I want to disable autosuspend for a single USB port. I have tested the following successfully:
sudo echo on > /sys/bus/usb/devices/1-2.4/power/control
How can I make this configuration permanent? Few sources mention
/etc/rc.local, but I am not sure if this is the correct place. The USB port I am targeting is part of a docking station, so it may not be present. Sure I can check if that USB device is present, but I am suspecting that there is a better solution. It is also possible to disable autosuspend for all ports using
/etc/default/grub. Is there a draw-back to disabling autosuspend for all devices? The only USB device that I have plugged in at all times (asides from keyboard and mouse) is a webcam. Will there be noticeably more power consumption if autosuspend is disabled?
