C922 Pro Stream Webcam Centos 7.2

[dcatkin]

Hey, guys, I had this webcam working on Scientific Linux, but I have wanted to install Centos 7 for a long time so I decided that after 1 year on SL I would finally take the plunge. I have not been able to get my Logitech C922 Pro Stream Webcam working. I use Cheese and ucview to operate the camera, and ucview will take video with no sound, and cheese is a black screen, I'm guessing it is a driver related issue. But everything worked in SL which if I am not mistaken is another spin from Red Hat much like Centos is.

Please give me some ideas to work off of.

First

Code: Select all

yum update

to 7.4, reboot and try it again.

I just did that.
I also ran this command and got.
