Everyone,
I was hoping to be able to plug the Logitech Brio in and have it
work,
but it did not. I can have it connect to a Windows 10 laptop and
have
it function, so I know the camera works.
The Centos 7.4 is recognizing it when I plug in the usb 3.0 cable.
The
results of dmesg demonstrated :

I am not seeing any new device driver in /dev/
Testing the programs 'cheese', 'vlc', and 'ucview' did not identify
the
camera.
I have used Logitech C922 webcams with Centos 7.4 which work just by
plugging them in.
Does anyone have any ideas as to how to make this 4K camera work on
7.4?
Thanks for your help!!!

You will need the appropriate device driver for it, and that driver
will
need to support the device.
Probably the easiest way to see if the device is supported on Linux
yet
is to boot the very latest kernel, which conveniently for you is
packaged in RPM format in the elrepo-kernel repository. Head over to
elrepo and set up the repository on your system:
http://elrepo.org/
then install the latest mainline kernel:
yum --enablerepo=elrepo-kernel install kernel-ml
Reboot to that new kernel (currently kernel-ml-4.13.12) and see again
if
the device is supported.

Phil,
Thank you very much.
After booting to the new kernel the camera worked very well with vlc
and ucview, but did not work with cheese.
I have never used a kernel from your website. After checking whether
some of the things I use for production work with the new kernel, I did
not identify any problems. Are there things I should consider, or is
this kernel reasonable to use on a production basis.
Thanks again!!!!
Greg
I would refer you to the release announcement:
http://lists.elrepo.org/pipermail/elrepo/2017-November/003904.html
Use at your own risk. But at least you now know the device is supported
upstream, so you can head over to Red Hat and file an RFE to request
support be backported from the upstream kernel.
