除了第一步必须，其他的对应链接https://blog.csdn.net/qq_26093511/article/details/78763824 Step1 在drivers/media/usb/uvc/uvc_driver.c中添加以下内容 { .match_flags = USB_DEVICE_ID_MATCH_DEVICE | USB_DEVICE_ID_MATCH_INT_INFO, .idVendor = 0x1E4E, .idProduct = 0x0109, .bInterfaceClass = USB_CLASS_VIDEO, .bInterfaceSubClass = 1, .bInterfaceProtocol = 0, .driver_info = UVC_QUIRK_PROBE_MINMAX },

其中 .idVendor = 0x1E4E, .idProduct = 0x0109, 对应我们使用的USB摄像头的VID和PID。

Step2： make menuconfig

  1. 进入 USB support

Device Drivers ---> [*] USB support ---> 如图配置：

  1. 选中 Multimedia support

Device Drivers ---> <*> Multimedia support ---> 如图配置：

  1. 再进入 Media USB Adapters

Device Drivers ---> <> Multimedia support ---> <>Media USB Adapters --->

如图配置

注：如果你不想编译成模块，可以把 UVC 这一项改为*，之后就不用 insmod 了

4 进入 V4L platform devices

Device Drivers ---> <> Multimedia support ---> <>V4L platform devices --->

如图配置

Step3 make uImage
