Nothing. You just ran out of continuous memory. This driver requires long chunks of continuous memory for USB data transfer. Please see this thread: http://www.spinics.net/lists/linux-media/msg43868.html As far as I remember, some things changed from 3.4 on the part that allocates memory there, reducing the risk of getting out of memory, but can't remember the specific details anymore.
