Hi, With a 3.15-rc3 kernel i seem to reliably trigger these warnings (which don't trigger on 3.14.2) when stopping a video stream. They don't seem to cause to much havoc because the devices are still usable after this. It seems to happen with both this syntek device as with em28xx devices. --

Hi, I'm hitting this warning on boot with a syntek usb video grabber, it's not clear to me if it's a driver issue of the stk1160 or a generic ehci issue. This is with a 3.15-mergewindow kernel (pull of Linus his tree of today). -- Sander [5.587759] [ cut here ] [
