linux-2.6/Documentation/usb/power-management.txt power/autosuspend This file contains an integer value, which is the number of seconds the device should remain idle before the kernel will autosuspend it (the idle-delay time). The default is 2. 0 means to autosuspend as soon as the device becomes idle, and -1 means never to autosuspend. You can write a number to the file to change the autosuspend idle-delay time.
