Agreed about the "correct" fix likely being on the USB side, but at least using printk_ratelimited() will avoid the log spamming, and avoid locking the machine, as you said. Will someone else take that approach and come up with a patch, or is this something I should try to take on myself? I could certainly test such a patch, if desired. Meanwhile, I'll look into reporting the USB bug, if it hasn't already been.
