Description:
|
||||
Each USB device directory will contain a file named
|
||||
power/level. 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.
|
||||
|
||||
This file is deprecated and will be removed after 2010.
|
||||
Use the power/control file instead; it does exactly the
|
||||
same thing.
