向驱动程序注册(/绑定/匹配)设备 [英] Register(/bind/match) a device with a driver

问题描述

我正在linux上编写一个USB驱动程序(用于游戏手柄)，当我将其插入时，ti会加载usbhid.我如何才能使它加载我的驱动程序(gp_driver)? 我做了取消绑定的usbhid并绑定到了我的驱动程序技巧，但我不想每次都这样做.

I am writing a usb driver (for a gamepad) on linux, and when I plug it in, ti loads usbhid. How can I make it so it loads my driver (gp_driver)? I did the unbind usbhid and bind to my driver trick, but I don't want to do it every single time.

我应该已经加载驱动程序了吗? 我应该在驱动程序中编写代码吗? 我的驱动程序中有供应商和产品ID.

Should I have my driver already loaded? Should I code something in my driver? I have the vendor and product id in my driver..

谢谢

推荐答案

您将要为设备创建udev规则，该规则可用于创建设备文件，设置设备文件的权限以及加载相关的驱动程序

You will want to create a udev rule for your device, which can take care of creating your device file, setting permissions on the device file, and loading relevant drivers.

# if no driver has claimed the interface yet, load ftdi_sio
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_interface", \
        ATTRS{idVendor}=="9e88", ATTRS{idProduct}=="9e8f", \
        DRIVER=="", \
        RUN+="/sbin/modprobe -b ftdi_sio"
