写一段USB代码

以下是一个简单的USB设备驱动程序，用于Linux操作系统中的USB鼠标：

#include <linux/module.h>
#include <linux/usb.h>
#include <linux/hid.h>

// 定义USB设备的厂商ID和产品ID
#define USB_VENDOR_ID 0x046d
#define USB_PRODUCT_ID 0xc52b

// USB设备驱动程序的初始化函数
static int usb_mouse_probe(struct usb_interface *interface, const struct usb_device_id *id)
{
    // 打印设备信息
    printk(KERN_INFO "USB Mouse (%04X:%04X) plugged\n", id->idVendor, id->idProduct);

    // 获取USB设备
    struct usb_device *dev = interface_to_usbdev(interface);

    // 打印设备描述符
    printk(KERN_INFO "USB Mouse: bcdUSB = %04X, bDeviceClass = %02X, bDeviceSubClass = %02X, bDeviceProtocol = %02X\n",
           dev->descriptor.bcdUSB, dev->descriptor.bDeviceClass, dev->descriptor.bDeviceSubClass, dev->descriptor.bDeviceProtocol);

    // 打印接口描述符
    printk(KERN_INFO "USB Mouse: bInterfaceClass = %02X, bInterfaceSubClass = %02X, bInterfaceProtocol = %02X\n",
           interface->cur_altsetting->desc.bInterfaceClass, interface->cur_altsetting->desc.bInterfaceSubClass, interface->cur_altsetting->desc.bInterfaceProtocol);

    return 0;
}

// USB设备驱动程序的退出函数
static void usb_mouse_disconnect(struct usb_interface *interface)
{
    // 打印设备信息
    printk(KERN_INFO "USB Mouse disconnected\n");
}

// 定义USB设备的ID
static struct usb_device_id usb_mouse_id_table[] = {
    { USB_DEVICE(USB_VENDOR_ID, USB_PRODUCT_ID) },
    { }
};
MODULE_DEVICE_TABLE(usb, usb_mouse_id_table);

// 定义USB设备驱动程序结构体
static struct usb_driver usb_mouse_driver = {
    .name = "usb_mouse",
    .probe = usb_mouse_probe,
    .disconnect = usb_mouse_disconnect,
    .id_table = usb_mouse_id_table,
};

// 设备驱动程序模块初始化函数
static int __init usb_mouse_init(void)
{
    int result;

    // 注册USB设备驱动程序
    result = usb_register(&usb_mouse_driver);
    if (result)
        printk(KERN_INFO "USB Mouse driver registration failed\n");
    else
        printk(KERN_INFO "USB Mouse driver registered\n");

    return result;
}

// 设备驱动程序模块退出函数
static void __exit usb_mouse_exit(void)
{
    // 注销USB设备驱动程序
    usb_deregister(&usb_mouse_driver);
    printk(KERN_INFO "USB Mouse driver unregistered\n");
}

// 设备驱动程序模块注册
module_init(usb_mouse_init);
module_exit(usb_mouse_exit);
