Since upgrading to F27 my logitech web cam no longer works. Here are the errors I see

I used cheese but it shows nothing useful.  It displays a snapshut of my desktop.  If it makes a difference I'm using mate desktop.

Anyone else have a webcam working under f27?

Any help is appreciated.

Thanks

No problem here.
PC is Thinkpad x260 with built in camera
uname -a:
Linux rwells-x260 4.14.11-300.fc27.x86_64 #1 SMP Wed Jan 3 13:52:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

cheese was installed by default when I installed Fedora 26 -> 27 and just works

lsusb -v gives the following about the camera:
