USB devices are identified by a combination of their `idVendor` and

`idProduct`. We can't be sure this combination in unique per equipment.

To still allow connecting multiple similar equipments, we complete the

identifier by a counter. The drawbacks are we can't be sure the equipments
|

|

will get the same identifiers after a reboot or a disconnect/reconnect.
