I wouldn't worry about it too much if the keyboard is functioning as it should... this "location“ thing isn't a very reliable source of where your devices are connecting to. To give you an example of mine, I have a usb audio DAC (external sound card) connected to a usb port, and the location says on the properties window is:
0000.001d.0003.001.000.000.000.000.000
like it tells me anything...
