如何获取IOUSBDeviceInterface的用户自定义名称

#include <IOKit/usb/IOUSBLib.h>

// 获取USB设备的接口对象
IOUSBDeviceInterface** getUSBDeviceInterface() {
    IOUSBDeviceInterface** deviceInterface = NULL;
    io_iterator_t iterator;
    io_service_t usbDevice;
    
    // 创建USB设备迭代器
    IOServiceGetMatchingServices(kIOMasterPortDefault, IOServiceMatching(kIOUSBDeviceClassName), &iterator);
    
    // 遍历迭代器，找到第一个USB设备
    usbDevice = IOIteratorNext(iterator);
    
    // 创建USB设备接口对象
    IOCreatePlugInInterfaceForService(usbDevice, kIOUSBDeviceUserClientTypeID, kIOCFPlugInInterfaceID, &deviceInterface, NULL);
    
    // 释放资源
    IOObjectRelease(usbDevice);
    IOObjectRelease(iterator);
    
    return deviceInterface;
}

// 获取IOUSBDeviceInterface的用户自定义名称
NSString* getUSBDeviceName(IOUSBDeviceInterface** deviceInterface) {
    UInt8 deviceName[256];
    kern_return_t result;
    
    // 打开设备
    result = (*deviceInterface)->USBDeviceOpen(deviceInterface);
    if (result != kIOReturnSuccess) {
        return nil;
    }
    
    // 获取设备名称
    result = (*deviceInterface)->GetDeviceProduct(deviceInterface, deviceName);
    if (result != kIOReturnSuccess) {
        return nil;
    }
    
    // 关闭设备
    (*deviceInterface)->USBDeviceClose(deviceInterface);
    
    // 转换为NSString对象
    NSString* deviceNameString = [NSString stringWithCString:(const char*)deviceName encoding:NSUTF8StringEncoding];
    
    return deviceNameString;
}

// 获取USB设备接口对象
IOUSBDeviceInterface** deviceInterface = getUSBDeviceInterface();

// 获取用户自定义名称
NSString* deviceName = getUSBDeviceName(deviceInterface);

// 打印用户自定义名称
NSLog(@"USB Device Name: %@", deviceName);
