BCD_DEVICE and Teensy Type

luni

I use the BCD_DEVICE field in the USB Descriptor to identify the type of the connected Teensy without having to start the bootloader first. However, I just noticed that the USB types MIDI XX and Flightsim types do not code the board type information in the BCD_DEVICE type but use a fixed 0x211 or 0x212 instead. Is there a technical reason for this or is it just some left over from the past? If so, could it be changed to code the board type like in the other Usb-Types?
