I have just installed 18.04 MATE. I have two cameras available, one built-in and the other a usb eye-cam. In 16.04, both were seen by cheese (Cheese->Preferences->Webcam). In 18.04, cheese only registers the built-in one. However, the other camera IS visible to guvcview and vlc. I have tried playing with dconf Editor without effect.
dsmesg reports:

Does anyone have any suggestions or is this just a bug?
Thanks
