USB_SUSPEND |

bool "USB runtime power management (autosuspend) and wakeup" |
| 25 |
depends on USB && PM_RUNTIME |

If you say Y here, you can use driver calls or the sysfs |
| 28 |
"power/control" file to enable or disable autosuspend for |
| 29 |
individual USB peripherals (see |
| 30 |
Documentation/usb/power-management.txt for more details). |
