Softer error when USB data bus cannot keep up

More often than I'd like, I start a capture that is waiting for a trigger. At some point, Logic decides the USB bus does not have enough bandwidth to handle all the data. When this happens a dialog box pops up and stops any running capture. This invariably makes me miss the trigger that I was waiting for and forces me to restart the whole sequence which often takes a while to setup.


IMHO, the "keep" vs "discard" option is just a waste of time.


The best implementation, imho, would be to simply mark a section of time as invalid, data lost, or automatically undersampled. If the data I really cared about was missed, then I can re-run the capture. But 99% of the time I'm sure the capture would have recovered if not for the hard error when the USB bus cannot keep up.

    In addition, it would be helpful to be able to prioritize channels. When Logic runs low on resources, it would stop measuring on lower priority channels to ensure it can keep sampling the high-priority channels.
