This file holds a power-level setting for - the device, either "on" or "auto". - - "on" means that the device is not allowed to autosuspend, - although normal suspends for system sleep will still - be honored. "auto" means the device will autosuspend - and autoresume in the usual manner, according to the - capabilities of its driver. - - During normal use, devices should be left in the "auto" - level. The "on" level is meant for administrative uses. - If you want to suspend a device immediately but leave it - free to wake up in response to I/O requests, you should - write "0" to power/autosuspend. - - Device not capable of proper suspend and resume should be - left in the "on" level. Although the USB spec requires - devices to support suspend/resume, many of them do not. - In fact so many don't that by default, the USB core - initializes all non-hub devices in the "on" level. Some - drivers may change this setting when they are bound. - What: /sys/bus/usb/devices/.../power/persist Date: May 2007 KernelVersion: 2.6.23 |
