USB3 cameras show 0 fps/black screen after few minutes of acquisition

We've seen certain cases where a USB3 camera that is recognized and operational in a system abruptly stop transmitting images (image window shows a black image, frame rate indicates 0 fps). This could be due to Windows switching the USB3 card to a low power mode. To ensure smooth operation, the "USB Selective Suspend" option should be set to "disabled". This is applicable to both laptops and desktops running Win 7 or higher. 

The "USB selective suspend" can be disabled by accessing the Power Options through Control Panel. Once here, go to your current plan settings, click on change plan settings, then access "advanced settings". Under advanced settings, you will find "USB settings" as an expandable menu option. Expand this option to access "USB selective suspend", which will be another expandable sub-menu item. Once expanded, you can then set USB Selective Suspend" to "disabled" for both "Plugged in" and "On Battery". This will ensure that the camera is never affected by the USB3 card switching to a power save mode.

    Hi James,

      I just noticed the comment as we don't have notifications enabled for comments yet but if you're still running into this, it is a packet size/packet delay issue and adjusting the packet size on the camera to match what is on your NIC should resolve it. If your NIC has jumbo frames, please enable that and then set a packet size in the camera that matches that setting.

    MMCSS settings would affect camera(regardless of I/F)'s streaming stop.

    For example, USB device connections/removing, sometimes Beep sounds affects camera's streaming.

    In this case, you can try settings below:

    * Disable MMCSS:

    a) Launch regedit
    b) Select "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\MMCSS"
    c) Double Click "Start" and open editing popup window.
    d) Change value from 2(Automatic) to 4(Disable), and press "OK"
    e) "File" -> "Close registry editor"
    f) Reboot the PC
