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 :-)
