I recently performed a planned upgrade of 20.04 LTS to 20.04.02 and subsequently lost most of the device drivers (I assume) - no sound (just says 'dummy output'), no usb camera, USB keyboard doesn't work, no usb headset and no wi-fi adapter found. (they were working previously of course).
If I goto software updater it says I'm fully up to date!
If I run lusb I can see:

So it can see them.. just doesn't seem to work. Does anyone know how to force Ubuntu to install all the missing software? Thank you in advance :)
