It does not matter what they are using internally, it's USB on the
outside and USB can be snooped under windows and the protocol
discovered. It's fairly trivial to do but I don't think this will be
required as it seems Hauppauge might disclose it. But even if they
don't, it's not a show stopper.
The USB "driver" can be a user space driver in the same manner as the
HDHomeRun. It's a similar driver too, some setup, go and catch the
encoded output. Simple.
