Dell Latitude E7450 webcam doesn't work w/ 18.04

Question

I'm new to Linux (forced myself to learn by installing it), but have about 20 years in Windows.

I got a used Dell Latitude E7450 with Windows and wiped it out, then installed Ubuntu 18.04. Most stuff works correctly but the integrated webcam doesn't: when I open Skype and check video, the led powers on, but no image shows up. Cheese shows blank and options greyed out.

hardinfo output shows an "Input device" identified as "SPCA2082 PC CAMERA".

Can you please assist on where should I look? I checked the Dell support site, but there's no specific Ubuntu driver for anything but the BIOS. Thanks very much in advance.

Below are some outputs from lsusb & lspci
