This file holds the time (in seconds) 8 the device must be idle before it will be autosuspended. 9 0 means the device will be autosuspended as soon as 10 possible. Negative values will prevent the device from 11 being autosuspended at all, and writing a negative value 12 will resume the device if it is already suspended. 13 14 The autosuspend delay for newly-created devices is set to 15 the value of the usbcore.autosuspend module parameter. 16
