Failed to load HDMI when we connect usb webcamera

Hi all,

       We are working on a customised board on RZ/G1E processor.We are trying to use usb webcamera in our board, when we are not connecting webcamera on bootup hadmi is working fine.But when we connect webcamera on bootup hdmi is not loading.If we connect web camera after board boots no issue.



usb web camera:logitech (C170)


Also when we try to display webcamera on hdmi using gstreaming the board is rebooting.when try to stream web camera video we are getting green display.


Thank you.
