Definitely not a selling point. But more and more frequent as products 
morph over time due to firmware changes (for better or for worse). 
Luckily these audio interfaces do not (yet?) NEED to communicate to the 
mothership to be able to move samples around.

Yes, I have to check the front panel again but I think the sampling rate 
indicator flashes while it is not yet locked to the new sampling rate 
(at least in the bigger interfaces, I don't remember what it does on the 
UltraLite).
