Thank you! I was unaware that a restore didn't do the firmware, but now that you say it, it displays that warning right in front of my face 
I've had this thing for 5 or 6 years and never needed to do a restore, I'll take that as a good thing, this hub is great despite this little hiccup.
For the record, I never actually tested it when I confirmed it above, I just did the restore and assumed that fixed it as I'm not at home to test it yet. Just did the restore via chrome's remote desktop thing. But now I'm sure this diagnostics restore will do it.
