我尝试运行sp96963.exe（您回复里的链接下不动，从官网访问旧固件版本下载的）降级到1.0.2.0，使用管理员权限执行解压后的HPFirmwareInstaller.exe，在“正在检测设备...”这一屏，无法检测到G5 DOCK，所有按钮都是灰色无法操作，如图：     等待约10分钟后依然如此，断开扩展坞，将扩展坞断电重连都试过，无法解决。 我测试了1.0.7、1.0.8、1.0.9的三个包，均没有此问题，马上就能检测到DOCK。目前固件已经从1.0.9.0降回1.0.7.0，但sp96963依然无法正常进行安装，请问是什么原因？   操作系统信息如下：     Microsoft Windows 10 专业版 10.0.19042 版本 19042   谢谢！
