https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252712 Bug ID: 252712 Summary: Webcam does not work when attached to xhci(4) but does attached to ehci(4) Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: nwhitehorn@FreeBSD.org I have a Logitech C925e webcam. When attached to the onboard xhci(4) controller (AMD 300 Series USB 3.0 controller), it does not provide any picture through webcamd, though does turn on. Data are clearly transferred, as the interrupt rate goes up dramatically when running pwcview. If I set uvc_driver.nodrop=1 in webcamd, I can see a small top portion of each frame, which gets smaller at higher resolution, suggesting that the transfers are being truncated after some number of bytes. If I install an ehci(4)-based PCI card and plug the webcam into that instead, everything works perfectly without tweaks. -- You are receiving this mail because: You are the assignee for the bug.home | help
