Having played with it last night, it seems that the microchip new HID USB stack is not compatible with robby's old software. It works fine on CF and not on RR, Driveline or TPMS doctor. So yeah it look like fresh plugin is needed for this.
If this is the case, it is probably best to change the message format it sends out to the PC. For each sensor it would be something like
[SENSOR ID], [PRESSURE], [TEMPERATURE], [BATTERY], [STATUS], [DATA AGE IN MINUTES]
