Notebooks usually have their own usb interface. As long as the interface is correct, the USB flash drive and mouse can basically be used normally. If there is no response, it may be because the interface is broken or the computer driver is not normal. Master Lu should check and repair it.

1. There are special USB 2.0 interfaces on both sides of the notebook, and you can insert a USB flash drive. The arrow in the figure below indicates that you can insert a USB flash drive as long as it is the same as the interface in the figure.

2. The arrow below is USB 3.0 interface, which is different from USB 2.0 interface. It is blue, and its transmission speed is 10 times that of USB 2.0 interface (provided that the U disk is also USB 3.0), so it can be backward compatible with USB 2.0.
