USB Host scanning has been broken since v2016.05.

This is due to all the USB changes that happened between v2016.03 and v2016.05, especially: 2ef117fe4f usb: Remove 200 ms delay in usb_hub_port_connect_change() a22a264ec3 usb: Change power-on / scanning timeout handling

So we need to increase the init delay to 2s using the usb_pgood_delay environment variable.
