Thanks for your response.
Very clear.
I will implement an application for individual identification.

Hello,

Historically gazell have been used for HID devices, where each pipe have been assigned for a specific purpose, e.g.:

pipe 0 - pairing

pipe 1 (synchronous) - mouse

pipe 2 (asynchronous) - keyboard

pipe 3-5 - other type of hid devices

So theoretically you could have for instance several keyboard using pipe2, but gazell did not need to differentiate them, so there is no way to identify which type of mouse or keyboard that was at any time using the various pipes.

If you need to differentiate them the easiest may simply be to add a random number in each packet sent from the controller->host, the random number is unique for each "controller". Such that when controller 1 send data, the first (or last) 2-4 bytes random unique number for the specific controller. This must be added by the application.
