such as open, close, read, and write, the Linux kernel accesses the functions provided by the driver through the file_operations structure. For example, when an application reads a device file, the kernel calls the READ function in the file_operations structure. To drive USB camera headers on the system platform, first compile the USB controller driver module into the kernel statically so that the platform supports the USB interface, and then use the camera to collect data, use insmode to dynam
