When the dancing carpet is plugged into the computer, USB cannot recognize it. The treatment method is as follows:

1, maybe the usb cable connected to the dance carpet is broken. The four terminals of the data line interface are used for charging and connecting data respectively. If one terminal is broken, you can't connect usb. You can try reconnecting with a new data cable.

2. There may be something wrong with the 2.usb driver. You can use source files to repair the system when you install it. Run the system, enter the system installation page, and click "one-click system repair" to realize system repair and restore the system to the state when it was just installed.
