True, user could trigger the issue by manually setting autosuspend delay to 0
before that patch,
Maybe a better Fixes commit would be:
2839f5bcfcfc ("USB: Turn on auto-suspend for USB 3.0 hubs.")
Both are from 2012 so not sure it really matters anymore
("USB: Turn on auto-suspend for USB 3.0 hubs.") was added to v3.4 kernel
("USB: set hub's default autosuspend delay as 0") was added to v3.8 kernel
Thanks
