Do an "ls -l /dev/video*" before plugging it in and then again after it's
recognized to see if any devices are getting created.

What is the output of "lsusb -v" when it's recognized.
To long to have it here. The result about the camera is attached.
Also use journalctl instead of raw dmesg to get more info and to see if any
services are picking it up.

To me, it seems that the camera uses the uvcvideo driver and the problem is
related to all those "not initialized" errors. But I've no idea how to fix
them.
Have you tried other USB ports? Do you have a USB hub you could try? Maybe
a different USB cable as well.
Yes, still the same behavior: sometimes it is recognized, sometimes it is not.
Never show up in the usable devices. One more thing I noticed is that once it
is recognized if I run multiple times the lsusb command it shows up with
different device number. E.g.,
>lsusb | grep IPEVO
Bus 003 Device 016: ID 1778:d120 IPEVO Inc. IPEVO VZ-X
>lsusb | grep IPEVO
Bus 003 Device 019: ID 1778:d120 IPEVO Inc. IPEVO VZ-X
And sometimes doesn't show up in the list.
