// There are multiple hubs here because without them, USB ports won't work
// if it's a chained hub device. From what I've read, most hubs are 4-port
// devices -- but there are 7-port hubs, which use 2 chained hub chips, so
// for all the USB ports to work on those hubs we have to have 2 hub objects
// managing them. I've decided to limit this to 2 hub objects.
