| # how this works | |
| # When you connect an input device, such as a keyboard or mouse, to your system, udev triggers various rules. | |
| # If the connected device is recognized as part of the input subsystem and has a power/control attribute, this | |
| # rule will set that attribute to "on", effectively disabling USB autosuspend for that device. | |
