Oh, right. Once again back to your definition of tracking ID that is
not so intuitive to me :-) In the end we might end up dealing with
three IDs: the device's tracking ID, the slot ID, and the Linux
tracking ID. Here, the first and the second are the same but will
they always be? I remember when Stantum used to provide us with 16
bit "device tracking IDs"...

Anyway, I have no more problem with this constant. Just with the
vocabulary :-)
