    For whatever it's worth, the most common issues with UVC cameras is lack of power. Consult your technical documentation for minimum voltage and current requirements then make sure you have enough to support your camera's operation. Otherwise, you'll be chasing these issues for a while.

    Hi,

    I have the same issue with my camera. @Chris-McCaslin or @Janus-Sanders any ideas?

    We also suspect that a long USB cable is causing a non-stable power transmission...

    I did some very basic research, so this may not be very accurate. It appears that your USB camera has audio that may be interfering with the USB drivers on the Omega Onion (again...not exactly sure). Try the following:

    1. Make sure the volume on the Camera is turned all the way down or off
    2. Use a USB camera that doesn't have audio

    And try again.

    From your error message, it appears that the USB camera disconnects and reconnects a couple times then finally fails.

    Thanks @Janus-Sanders

    We are going to disable the mic of the camera via a firmware update and I'll let you know

    UPDATE: It turns out we had an issue in our PCB design that was causing electromagnetic noise. This was resetting the USB HUB.

    usb 1-1: USB disconnect, device number 2

    The issue was not in the camera but in the PCB design affecting the USB HUB
