Device initialization with kernel 3.2, video and audio working
djh - you may wish to try a non-USB3 port. There has been a history of problems with the newer xhci driver and it would be good to know whether you see the same behavior on a standard USB 2.0 port. Tryed a USB2 port, but that makes no difference: if xhci is available, it is used by the kernel. If xhci is disabled in the kernel config, audio is working (sort of) on all ports: arecord/aplay gives sound (hurrah!), but as soon as the channel is changed in tvtime (or QTV4L2), sound is gone. It doesn't help to restart arecord/aplay, I have to terminate tvtime and completely restart again. Is this expected and proper behavior? So your assumption is correct, the freeze is related to USB3. Should I file a USB bug report? It sounjds liek there are a couple of different problems there, do file the USB one as well Hi, did you fix the issue ? i'm having same tuner and same issue @ 87711 did you try : modprobe em28xx i2c_scan=1 ? No, I switched to another device... which also has the ability to freeze the kernel :) |

Analog TV video stream is displayed, tested with tvtime and qtv4l2, but as soon as em28xx-alsa is accessed, USB freezes. The same device is working (video and audio) at least until kernel 3.2 on the same hardware (Intel DH87RL, BIOS RLH8710H.86A.0320.2013.0606.1802).
