We are using zynq Ultrascale + MPSoC with custom board. Our board has 2 USB ports(Host 2.0 and device 3.0), 2 SDI(one input and another output). Kernel version on board is 4.19.0 and In host PC 5.4.0-58-generic. Final project according to customers requirement is Streaming 1080p video taking input from SDI and taking output from USB(device). Currently We are trying with connecting C922 Pro Stream Webcam to USB(host) port.This creates /dev/video0 node. Then modprobe g_webcam. This creates /dev/video1. Using the application https://github.com/wlhe/uvc-gadget At host side /dev/video0 is created. When I try to display using application such as guvcview, at the device side, getting below attached log. I need some more input so that I can move forward with this project. USBGITLOG.txt host
