切换至DriverKit USB Transport-VendorID后iPadOS驱动不显示求助

此前使用「DriverKit USB Transport (development)」时，驱动可正常显示在应用设置中。在获得「DriverKit USB Transport - VendorID」使用权限后，已完成以下操作：

• 更新开发者后台的App ID配置
• 移除所有开发权限
• 更新配置文件
• 修改驱动的.entitlements文件

原.entitlements内容 #

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.developer.driverkit</key>
    <true/>
    <key>com.apple.developer.driverkit.transport.usb</key>
    <array>
        <dict>
            <key>idVendor</key>
            <string>*</string>
        </dict>
    </array>
</dict>
</plist>

修改后的.entitlements内容 #

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.developer.driverkit</key>
    <true/>
    <key>com.apple.developer.driverkit.transport.usb</key>
    <array>
        <dict>
            <key>idVendor</key>
            <integer>1111</integer>
        </dict>
    </array>
</dict>
</plist>

现象与日志 #

应用可正常安装在搭载M芯片的iPad上，但驱动并未出现在设置中，相关日志如下：

排查思路与解决方案 #

• 核对VendorID一致性：从日志可见，installd序列化后的entitlements中idVendor为3034，但本地修改的文件中是1111，二者完全不匹配。需检查：
  • 开发者后台App ID配置中是否正确添加了目标VendorID（1111）
  • 配置文件（Provisioning Profile）是否基于更新后的App ID重新生成并下载
  • Xcode是否加载了最新的配置文件，可尝试清理Derived Data后重新构建
• 确认权限与签名匹配：确保开发者后台的App ID已启用「DriverKit USB Transport - VendorID」权限，且驱动的.entitlements中idVendor的类型（integer）与后台配置一致，不能混用字符串类型
• 排除Sandbox日志干扰：日志中的沙箱报错属于系统常见限制，不会直接导致驱动不显示，无需优先处理
• 验证系统扩展激活流程：检查主应用代码中是否正确调用OSSystemExtensionManager相关API发起驱动激活请求，并处理激活回调的错误信息，确认激活流程无异常
• 重启设备重试：卸载应用后重启iPad，再重新安装并测试，确保配置文件生效
