Hi,
I'll try and reproduce this - can you give me a list of which steps you followed to install the camera? Ideally from a clean system.
Cheers!
On a Ubuntu 16.04:
Ok, when I have some time I'll try on a clean ROS install. It may be worth experimenting with something like Docker to keep things repeatable.

@nathangeorge1 Is this also related to the issue that got fixed with a clean install, or something separate?
likely something separate but I'll check
even with copying the udev rules and doing a clean install, this error persists
Can you open the camera in eg. Opencv? Or something other than ROS?

I was able to open it using the e-con Windows utility

Could you try with qv4l2? (sudo apt install qv4l2
)
That should help isolate if it's a problem with ros/libuvc or if you're missing a driver perhaps. Clearly the camera itself is fine, but we need to check on the same machine/OS you're having issues with.
I seem to have the latest version already
This issue can sometimes happen if the wrong device is selected by the driver (for example a built in webcam). The device to use can be defined in the launch file using the 'device' parameter:
roslaunch i3dr_deimos deimos.launch device:=/dev/video1
