Do you know which chipset is used in the hub?

OK, let's try to get some more info.

Please recompile your kernel with
option USB_DEBUG

and add these entries into your /etc/sysctl.conf file:
# USB debugging
hw.usb.ohci.debug=1
hw.usb.debug=1
hw.usb.uhub.debug=1

Now, reboot the system without the hub attached.
When system is running, attach the hub without any other USB devices
and watch messages on the console.
It would be interesting to know what you see.
