On my command line only Ubuntu machine, the login prompt occasionally shows a warning:
Ubuntu 12.04 LTS myserver tty1 myserver login: [833747.589882] ipheth: ipheth_rcvbulk_callback: urb status: -71
Nothing is obviously wrong with the system, and I can enter my username and password without issue.
What does this message mean and should I be worried about it?
Edit: I've found plugging in and then removing my iPhone from the computer causes this message. I'm still looking for what it means.
