Just as a point of interest, the patch from Andiry Xu in the thread "Re: [PATCH] usbcore: Do not disable USB3 protocol ports in hub_activate()" seemed to be addressing my issue, so I applied his patch to my rc6 kernel ( though using (1 << USB_PORT_FEAT_SUPER_SPEED) instead of the USB_PORT_STAT_SUPER_SPEED define which does not appear in rc6. Seems to have fixed it for me, so I'll assume that this is already being addressed elsewhere! Thanks. Adam. On Friday 07 May 2010 09:07:09 you wrote: > Am Freitag, 7.
