Accessing the audio capture device (Em28xxAudio) of a USB TV adapter (Hauppauge HVR-900) causes a complete USB freeze (see lspci/lsusb and logging extract at https://bugzilla.kernel.org/show_bug.cgi?id=65021).
Tested with various kernel releases up to 3.12 (currently in use is 3.11.8). This device is working at least until kernel 3.2 with the same hardware (Intel DH87RL/Haswell, BIOS RLH8710H.86A.0320.2013.0606.1802). Switching from a USB3 to a USB2 port doesn't change anything; if xhci is available (xhci and ehci compiled into kernel), it is used and the bus freezes. If ehci is forced by disabling xhci completely, the capture device is working again. Any feedback welcome. -- Diese E-Mail wurde aus dem Sicherheitsverbund E-Mail made in Germany versendet: http://www.gmx.net/e-mail-made-in-germany -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
