Say Y here if you want the USB core to spawn a new thread for
every USB device that is probed. This can cause a small speedup
in boot times on systems with a lot of different USB devices.
This option should be safe to enable, but if any odd probing
problems are found, please disable it, or dynamically turn it

* usb_autoresume_device - immediately autoresume a USB device and its interfaces
* @udev: the usb_device to autoresume
* @inc_usage_cnt: flag to increment @udev's PM-usage counter
*
* This routine should be called when a core subsystem wants to use @udev
* and needs to guarantee that it is not suspended. In addition, the
* caller can prevent @udev from being autosuspended subsequently. (Note
* that this will not prevent suspend events originating in the PM core.)
* Examples would be when @udev's device file in usbfs is opened (autosuspend
* should be prevented until the file is closed) or when a remote-wakeup
* request is received (later autosuspends should not be prevented).
* and needs to guarantee that it is not suspended. No autosuspend will
* occur until usb_autosuspend_device is called. (Note that this will not
* prevent suspend events originating in the PM core.) Examples would be
* when @udev's device file in usbfs is opened or when a remote-wakeup
* request is received.
*
* @inc_usage_cnt should be 1 to increment @udev's usage counter and prevent
* autosuspends. This prevention will persist until the usage counter is
* decremented again (such as by passing 1 to usb_autosuspend_device).
* Otherwise @inc_usage_cnt should be 0 to leave the usage counter unchanged.
* Regardless, if the autoresume fails then the usage counter is not
* incremented.
* @udev's usage counter is incremented to prevent subsequent autosuspends.
* However if the autoresume fails then the usage counter is re-decremented.
*
* Often the caller will hold @udev's device lock, but this is not
* necessary (and attempting it might cause deadlock).
*
* This routine can run only in process context.
