Tashkinov" To: linux-media@vger.kernel.org Subject: Intermittent Logitech C510 problems (with kernel OOPSes) Message-ID: Sender: linux-media-owner@vger.kernel.org List-ID: Hi, I posted a bug report almost a year ago and since it's got zero attention so far I'm writing to this mailing list. My problem is that video capturing doesn't work on Logitech C510 webcam in some cases. Mind that audio input always works. Video capturing is guaranteed not to work after I reboot from Windows 7. In rare cases it doesn't work when I cold boot straight into Linux. When I try to capture - either there's no signal and capturing fails to initiate or I get a black screen (a LED on the webcam doesn't turn on in both cases). If I rmmod ehci_hcd and then modprobe ehci_hcd and uvcvideo, then everything starts working again. https://bugzilla.kernel.org/show_bug.cgi?id=67551 -- Best regards, Artem
