Because the move to unified major numbers was done after its addition.

Ideally we would make all MI major numbers the same, but the real world
is not a friendly place for ideals :)

While reading the code, though, I was wondering how difficult it would
be to have an ucom(4) attaching to this device instead of mostly
replicating all the code.  AFAICT, it should be possible to do that by
adding a few methods to ucom_methods and making ucom(4) use them
instead of making calls to usbd_* at the relevant places.

That would save you a lot of documentation as to where to find the
relevant device node, at least ;)

Of course, I'm really no expert of the USB code, so I might be missing
something.
