It's really strange because on my previous installs on the same PC, of Ubuntu 16.04, as soon as I connected the camera, it was detected. Very quickly in fact.
On my latest install of this OS though, nothing.
Here's the output from the lusb
command:
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

As you can see the camera is there. But it's simply missing from File explorer.
