[Originally reported at https://bugzilla.kernel.org/show_bug.cgi?id=84611, gregkh told me to report it here] My brother's USB 3.0 stick is only recognized as USB 2.0. I reproduced this bug in kernels 3.14.15, 3.16, and 3.16.2; as built by Debian. It used to work correctly in 3.14-rc6. The data below is from 3.14.15.
