lesto:
è bella l'idea della HIS, ma come viene vista? joystic ad X assi, dove X sono i valori da spedire?
No è un canale dati HID, usa due endpoint da 64 byte, uno IN e uno OUT, tramite i quali vengono scambiati i dati della telemetria e dei comandi di configurazione, ti allego il report della configurazione ricavato con USBview.
