iphone disconnects from Prius C's USB after a few seconds

For years, my iphone has worked with my Prius C's USB connection. Starting a few days ago, the following behavior consistently happens:

Plug phone into USB
Car connects
Music plays for about 10 seconds
Connection is lost

I cannot then re-establish either a USB nor Bluetooth connection at that point.

What happened in the latest iOS release that broke backwards compatibility with USB connections, and will this be addressed in a patch release quickly? Having to decide between recharging my phone and having driving directions is pretty bad, especially since my iphone's ability to hold a charge has been rapidly declining.

One possible stopgap solution would be a setting to disallow USB data connections while still allowing USB recharging - then I could recharge my phone and connect via bluetooth if and only if Prius C audio software doesn't get confused by such.
