*Hi Team,*

*Good Morning/Afternoon/Evening.*

I connect two usb webcameras and one mouse, one keyboard to  xhci
controller, which has 4 usb v3.x ports.
Here, keyboard and mouse works fine without any issue.
But out of two cameras, only one camera works( I mean when I click preview
only one camera show and one camera show blank )

*Debug log:*
