As of the 2.6.35 kernel, the level file is depreciated and now replaced by control.
The auto state is the normal state in which the kernel is allowed to autosuspend and autoresume the device.
In kernels up to 2.6.32, one could also specify suspend, meaning that the device should remain suspended and autoresume was not allowed. This setting is no longer supported.
More details can be found in the current Power management for USB kernel documentation.
