Is that the correct breaker commit? It seems to me that it marks only the commit which turned the problem into the default. It was always possible.

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
