There are two physical hubs in the Iyonix. The USB2 hub is a virtual one.
Any devices that are USB2 capable will show under the USB2 hub regardless
of which physical USB port they are plugged into.
If you were to plug in an external hub, as long as that is USB2 capable
the same rules apply. If you plug a USB2 capable device into a USB1
external hub then it will only run at USB1 speeds.

Try running !USBKick (see sig.) as part of your boot sequence.
There are a few mice that stop working if you happen to move them while
the device information is being read. I have a Belkin mouse that exhibits
this problem so I stopped using it.
