You talk about USB CDC, Communications Device Class.
[...]. Or it
is "too open". I.e. vendors like FTDI or Profilic are not able to
"lock in" customers by folowing a generalized device class.
I'm inclined to doubt that's it, because the same thing hasn't happened
with video. The two USB cameras I own - one built into a laptop and
the other a cheap plug-in camera - are video devices, following the
video device spec (as far as I've been able to tell so far; I haven't
actually got code to drive either one yet, but the descriptors match).
And I can't see any reason it'd happen with serial but not video.
