Tried that but I don't quite get it. I can see
Hub Port Status:
   Port 1: 0000.0100 power
   Port 2: 0000.0100 power
   Port 3: 0000.0100 power
   Port 4: 0000.0100 power
   Port 5: 0000.0303 lowspeed power enable connect
   Port 6: 0000.0100 power

But I cannot match 0000.0303 to a device. Can you give me an example?
