linux免驱USB摄像头内核配置

Device Drivers --->
<> Multimedia support --->
<> Video For Linux
[ ] Enable Video For Linux API 1 (DEPRECATED)
[] Video capture adapters --->
[] V4L USB devices --->
<> USB Video Class (UVC)
[] UVC input events device support

 

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：

2. 选中 Multimedia support

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

3. 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
