Looks like whether or not jack sensing works depends on the device itself, but there is a mechanism to propagate the change in setup in the USB Audio 2.0 spec
Some recent Windows 10 beta added partial support for USB Audio 2.0. Earlier Windowses implement only USB Audio 1.0, which does not mention jacks.
" A change of state in the audio function is most often caused by a certain event that takes place. An event can either be user-initiated or device-initiated. User-initiated jack insertion or removal is a typical example of a user-initiated event. "
There are not many USB Audio 2.0 devices, and I'm not aware of any that actually implements this.
