| 5 | Description: |
| 6 | Each USB device directory will contain a file named |
| 7 | power/autosuspend. This file holds the time (in seconds) |
| 8 | the device must be idle before it will be autosuspended. |
| 9 | 0 means the device will be autosuspended as soon as |
| 10 | possible. Negative values will prevent the device from |
| 11 | being autosuspended at all, and writing a negative value |
| 12 | will resume the device if it is already suspended. |
| 13 | |
| 14 | The autosuspend delay for newly-created devices is set to |
| 15 | the value of the usbcore.autosuspend module parameter. |
