Those are USBHID SET_REPORT Request when changing TrackPoint Stick sensitivity.
Only thing that's changing is:
- IRPID which is bytes 2 to 9 which is a pointer to something so that's to be expected I guess.
- Byte marked by ^^ is most certainly the sensitivity value being sent to our TrackPoint keyboard.
Min sensitivity:
