     326== Linux USB Auto-suspend
     327USB autosuspend is problematic with several embedded SoC's due to host controller chip errata. This is the case for both the i.MX6 on Ventana and the CN80XX on Newport. To work around these errata we find it safest to just disable USB autosuspend with a kernel command-line argument of 'usbcore.autosuspend=-1'. This is done in several of our bootscripts.
