I know. I am pretty sure that I did a cold boot, and that I tested for /dev/video* after booting. Since I reported the problem, I have continued using the official Fedora kernels for day-to-day work, and I use the test kernels only for short periods for testing. I have been checking the webcam every day out of curiosity when I boot my laptop in the morning, and maybe 1 out of 10 times the old scheme works. In any case, I just did the procedure again, taking better care. cold boot from kernel 5.6.6.localversion14 no /dev/video ls: cannot access '/dev/vid*': No such file or directory lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub sudo ls -l /sys/kernel/debug/usb/usbmon total 0 -rw------- 1 root root 0 May 1 00:03 0s -rw------- 1 root root 0 May 1 00:03 0u -rw------- 1 root root 0 May 1 00:03 1s -rw------- 1 root root 0 May 1 00:03 1t -rw------- 1 root root 0 May 1 00:03 1u -rw------- 1 root root 0 May 1 00:03 2s -rw------- 1 root root 0 May 1 00:03 2t -rw------- 1 root root 0 May 1 00:03 2u restore ehci-pci.ko lsusb unchanged with only 2 devices insmod /lib/modules/$(uname -r)/kernel/drivers/usb/host/ehci-pci.ko cat /sys/kernel/debug/usb/usbmon/3u > usbmon3.txt & cat /sys/kernel/debug/usb/usbmon/4u > usbmon4.txt & no /dev/video lsusb Bus 004 Device 003: ID 093a:2510 Pixart Imaging, Inc.
