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
off in the /sys/module/usbcore/parameters/multithread_probe
