Cheese not working; error not enlightening

Hi everyone,

recently the application Cheese has stopped working for me. I run it from the command line, a bunch of errors spring up, the application window pops up, I can see my past pictures, but it is just black in the space where it would normally show what's my machine's built in webcam is seeing. It was working until about a week ago, so I assume I still have the drivers (unless they're outdated or something). Here are the errors it returned:

[declan@buttzmachine ~]$ cheese 

** (cheese:9096): WARNING **: cheese-main.vala:251: Error: No device found


(cheese:9096): cheese-CRITICAL **: cheese_camera_device_get_device_node: assertion `CHEESE_IS_CAMERA_DEVICE (device)' failed

** (cheese:9096): CRITICAL **: cheese_preferences_dialog_setup_resolutions_for_device: assertion `device != NULL' failed

I googled these errors but found no solutions. Well, one guy with the same error realized that his problem was that his webcam was simply off, and to turn it on you hit [Fn]+[F4]. For me, the button with the little camera symbol is Esc, so I hit [Fn]+[Esc] and recorded the dmesg output before and after (I keep including the same stuff after waking up from suspend so you can see what has been added by the last action):

Before:

After hitting it again:

However, I try running Cheese in between each press, and I get the same error. What can I try?

Thank you!
