Should this fix go > through the USB or some media tree? Media drivers go via the media tree. You should notice that we are currently receiving around 100 patches per week there. It may take some time for people to review, but the patches are queued at patchwork, so sooner or later someone will review and apply, if nobody did it already: https://patchwork.linuxtv.org/project/linux-media/list/ That's said, I'm not seeing this patch there: https://patchwork.linuxtv.org/project/linux-media/list/?series=&submitter=&state=*&q=pvrusb2&archive=&delegate= It sounds that, for whatever reason, the patch never arrived patchwork. Please re-submit it and check if media patchwork got it. If not, perhaps you just found a bug with patchwork 2.1 :-) (we upgraded from version 1.0 to 2.1 at the beginning of this month) Thanks, Mauro
