well, the IR tower is fired when I tested out with different powered hubs. I
used 2.0 powered hub, the same symptom occured... the OS crashed in the
identical fashion. When I used 1.0 powered hub, the tower mysterably ceased
to response, then the OS does not even recognize the tower. I thought I
might have supplied too much power... but I tested with the mouse with the
same 1.0 hub, it worked fine with the same level of power supply. I guess I
would have to order a new one!?
So, hope Bob has better luck!
