That looks perfectly fine. Are there any messages after this? You may
need to wait 5 or 10 seconds.
Also, are you saying the hub is not detected correctly or that any
devices connected to it are not detected correctly?
What's most interesting about this is that it's a real 9 port hub. Some
of the ports may be fixed, but it's more than 7 ports. This is what I
was lookin for atleast.
