Since the upgrade to the 5.10.-oem kernel my USB Webcam/Microphone no longer works. Also, the command "lsusb" simply seems to hang and never returns. Everything was still working with the 5.6-generic kernels. Is this a known problem? I could not find any reported issues in this regard.

I would like to switch back to the latest 5.6-generic kernel, what is the safest way to do re-install older kernels without breaking my setup?

Current Kernel is 5.10.0-1019-oem #20-Ubuntu SMP. lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal

See launchpad bug reports 1918670 1920032

Reboot computer and press ESC key prior to Ubuntu spinner to open the grub menu

Select Advanced options from grub menu to show list of available kernels

Select known working kernel (in my case it was 5.10.0-1016-oem)

After computer finishes booting up open synaptic package manager

sudo apt install synaptic (if not already installed)

Under Sections heading select Kernels and modules and sort for your installed kernels

Select the 5.10.0-1019-oem kernel images to be deleted

select your preferred kernel 5.6? for reinstallation

Select Apply changes

After closing out of synaptic, for good measure I updated grub just to make sure things looked right before rebooting the computer

sudo update-grub

reboot
