Comment 36 for bug 17881

I'm not sure if I have the same problem, but it's quite similar and has happened on two different machines (both running Feisty), multiple USB ports, different logins, and with two completely different MP3 players.

I start to copy a significant amount of files, and after a short time I get all the symptoms of the device having been unplugged. This happens about one time in ten, perhaps more often if I start copying several folders in parallel.

I glanced in dmesg the first time it happened and nothing seemed out of the ordinary, it looked as if I had just unplugged the drive (at the time I assumed I had just bumped the cable).
