Here is the output when it fails. The "Unable to dequeue buffer: no
such device" message happens hundreds of times.

There should have been some USB message before that started.

It's resetting for some reason. Here it reconnects.

That's interesting and might be relevant.
Find the log lines before the dequeue errors start to see what happened.
