ZYNQ UVC：Unable to implement UVC

[66cavy]

PURPOSE: Recently, I want to realize USB3.0 image data transmission based on zynq, and I want to use UVC to realize it. Just as Xilinx wiki provides ideas, the reference website is：https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/2046001302/Building+Linux+usb+device+drivers+with+2021.1#UVC-Gadget(如图1所示)。

PROBLEM: After the virtual machine is ready, as shown in Figure 2 and figure 3, the effect of the board test is shown in Figure 5. It is found that it has been stuck in "v4l2: 2 buffers allocated", as shown in Figure 4. At this time, the camera software cannot search for "USB webcam": Picture 2： Picture 3： Picture 4：
