HP prime updating problem

[Chinese]

My hp prime cannot enter recovery mode.I press Symb while booting.However, it gets stuck after the blue HP logo appears. And there is no other words in the screen. If I start it normally , the connectivity kit cannot update my calculator either. The progress bar has no response ,and it just displays "Waiting for connection".But it can detect the calculator and get the information successfully. I connect my calculator to USB 2.0 port. My computer operating system is Windows 10. What should I do to solve the problem?thanks
中文版：计算器无法进入恢复模式，会卡在显示有蓝色惠普logo画面的那里。我如果不进入恢复模式直接启动的话，那么连接套件还是无法更新，进度条没有任何反应，只是显示​等待连接。但是，连接套件可以成功侦测到计算器并且获取计算器上面的数据。我使用的usb2.0端口，电脑系统为win10，我该如何去解决问题。谢谢
