Hello About the problem of sc2 pro USB connection to the computer

I bought it for two months, and there has been a disconnection problem until this week. The situation is more serious. Sometimes Driver can’t recognise sc2, and sometimes it suddenly loses torque in the game. After that, Driver has been showing connection and disconnection. Have you ever encountered such a problem? Or the solution? I have replaced six brand-new USB cables. The USB of the bottom plate of the test computer has all been connected. Or active USB hub. The situation has not changed.
