Hello, As the title suggest I am trying to use a camera plugged into a USB3 socket. it works fine plugged into a USB2 socket but luvcview gives the following error: --- luvcview -d /dev/video0 luvcview 0.2.6
SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 libv4lconvert: warning more framesizes then I can handle! libv4lconvert: warning more framesizes then I can handle!

Exiting ... --- I've also tried cheese which has the following error: --- cheese libv4lconvert: warning more framesizes then I can handle! libv4lconvert: warning more framesizes then I can handle! libv4lconvert: warning more framesizes then I can handle! libv4lconvert: warning more framesizes then I can handle! libv4l2: error turning on stream: Invalid argument --- The motherboard is running an Intel P55 chipset with the USB 3.0 provided via a NECD720200F1 chip. The cameras all work fine when plugged into the USB2.0 socket provided by the Intel chipset. Below is the ouput from the camera. Output from LSUSB with a Logitech : Bus 017 Device 002: ID 046d:0825 Logitech, Inc. The same thing happens with a Philips SPC620NC camera, LSUSB is : Bus 017 Device 002: ID 0471:0333 Philips (or NXP) SPC 620NC PC Camera Is this something to do with the camera trying to push too much data down the higher bandwidth USB3? Any help or hints much appreciated.
