to solve the usb device enumeration race on boot, usbd creates /env/usbbusy on startup and once all devices have been enumerated and readers have consumed all the events, we remove the file so nusbrc/bootrc can continue. this makes sure all the usb devices that where plugged in on boot are made available.
