https://bugzilla.kernel.org/show_bug.cgi?id=207219 --- Comment #11 from William Bader (williambader@xxxxxxxxxxx) --- I see the instructions for making a usbmon trace in an earlier comment. How do I keep the ehci-pci driver from getting loaded, and how do I load it manually? Is this how to keep it from being loaded? # echo blacklist ehci_hcd > /etc/modprobe.d/ehci_hcd.conf # cp /boot/initrd.$(uname -r).img save # mkinitrd -o /boot/initrd.$(uname -r).img $(uname -r) # reboot How do I load it? I was guessing modprobe, but "lsmod | grep hci" shows only sdhci, cqhci, and sdhci_pci. "Set up your system so that the ehci-pci driver doesn't get loaded automatically, in either the running system or the initrd image. Then when the system has started up, start up a usbmon trace from the 0u file (that is, all buses) and load ehci-pci manually. That way we can see exactly what happens when the webcam gets initialized for the first time." -- You are receiving this mail because: You are watching the assignee of the bug.
