This appears to be a compatibility issue w/ the hub...  If I reboot w/
the hub plugged it, it will go into this weird mode.  If I unplug the
hub, but leave the hub powered, it will still do it... But if I unplug
the hub and remove it's power (cold booting the hub) and plug it in,
it works fine...

If I reboot w/o the hub powered, but plugged in, it fails, but when
I unplug (now hub has no power) and plug it back in, it works fine...

Does this shed any light on the issue?

The only BIOS option related to USB is the keyboard in BIOS/DOS option.
