If you really want to do it this way, at least add a > "/* fall through */" so that it's obvious that this is not a mistake. Done here, will post again. I'd like you to try the "ehci-hcd: complete iso urbs ASAP for number_of_packets != (n * 8) also" http://marc.info/?l=linux-usb-devel&m=119444869917392&w=2 with snd-usb-audio. snd-usb-audio uses number_of_packets equalling multiples of 8 currently when transfering over USB 2.0, no? If so, with above patch that "multiples of 8"-thing could go away and snd-usb-audio could achieve up to 8 times less userspace-activation-jitter in low latency setups like 128 frames/period, 2 periods. thanks, Karsten _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
