I don't think there is an USB signal for each shutter change. From what I've read on several topics in this forum, I think that only the emitter deals with sending signals using its integrated clock.

USB signals are used less frequently and only to adjust any shifting between the vertical refresh and the shutter glasses. If you wanted to insert a signal for DDC glasses for example, I don't think it would be possible that way.

You may have a look at these topics to get more information :
