|In the patch "usb: simplify usbport trigger" together with
|"leds: triggers: add device attribute support" caused an
|regression for the usbport trigger. it will no longer
|enumerate any "ports" (i.e the sysfs directory stays empty)
|if the usb host drivers are fully initialized before the
|usbport trigger was loaded.
