--- Comment #15 from William Bader (williambader@hotmail.com) ---
Created attachment 288811
  --> https://bugzilla.kernel.org/attachment.cgi?id=288811&action=edit
logs from /sys/kernel/debug/usb/usbmon/3u and 4u

I made the logs. Here is what I did:
use make menuconfig to set
 CONFIG_USB_EHCI_HCD=m CONFIG_USB_OHCI_HCD=m CONFIG_USB_OHCI_HCD_PCI=m
CONFIG_USB_UHCI_HCD=m CONFIG_USB_XHCI_HCD=m CONFIG_USB_XHCI_PCI=m
build, install, and cold boot with new kernel
confirm no /dev/video
rename /lib/modules/$(uname -r)/kernel/drivers/usb/host/ehci-pci.ko
sudo mkinitrd --force /boot/initramfs-$(uname -r).img $(uname -r)
Creating: target|kernel|dracut args|basicmodules
dracut-install: could not get modinfo from 'ehci_pci': No such file or
directory
ls -l /boot
35318679 Apr 28 21:34 initramfs-5.6.6.localversion14.img <- before
35314182 Apr 28 21:43 initramfs-5.6.6.localversion14.img <- after
cold reboot
I did not have a mouse. I could log into Mate desktop but I couldn't find a way
to launch an xterm.
Switch to a text console.
no /dev/video
cat /sys/kernel/debug/usb/usbmon/3u > usbmon3.txt &
cat /sys/kernel/debug/usb/usbmon/4u > usbmon4.txt &

restore ehci-pci.ko
insmod /lib/modules/$(uname -r)/kernel/drivers/usb/host/ehci-pci.ko
