Extend the USB transmit timeout from 5 ms to 50 ms. We are getting spurious unsubscribes due to the timeout while still being connected, so 5 ms is not long enough. Let's increase by 1 order of magnitude and see how it goes.

Hmm... EV3 seems to need an even longer timeout. I wonder if this means there is something else blocking this from updating or if the app really is taking that long to service the IN endpoint.
