Is this even english ;) -The fiq_fsm handler is incorrectly performing transfers to high-speed isoc OUT endpoints. It appears that it's blindly transferring data every microframe instead of strided per 2^(n-1) microframes. With Isoc IN endpoints, you can request data every microframe and the device just responds as-and-when. This is why nrpacks=1 worked - one isochronous transfer p er URB which hid the bug. Without FIQ support, microframe jitter will cause variations in timing of the OUT packets which will probably cause sample rate skew. I'll look at implementing strided transfer support.- ------------------------------------------------------------------------ psketch's Profile: http://forums.slimdevices.com/member.php?userid=56555 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
