Hello, before doing any kind of serious task I just suggest you to check the USB port of the device is correctly or not. Sometimes there is passivity that this device is to be damaged due to some UN carefully handle it. Hence I think you need to first check the port and then if the problem is present into that port then replace it. This will be solved the permanent hardware problem. Then first try this solution.

The other way is to be checking the USB controller of the system. It could be possible that the damage happens into that system and hence this will be detecting the device in few seconds. If there is some damage happens into that USB controller which is present into the Device manager, then reinstall the driver of this USB controller. It will be helps you to solve this problem. This is the special type of solutions when we something change the system setting.
