Operation method
We can try a new USB socket first. No matter on the front panel or on the back of the chassis, the power supply and electrical performance of each USB socket are somewhat different for some reasons, and the latter is better than the former.
For desktop computers, if the USB interface on the front panel cannot be used, and the USB circuit board or socket on the back motherboard can be used, it is that there is a problem with the USB circuit board or socket on the front of the chassis. You can consider replacing it.
Today's computers all have USB 3.0 interfaces (usually blue) and need special drivers. If only the USB 3.0 interface (usually blue) cannot be used, it is likely that the system does not have USB 3.0 drivers installed. You can install drivers through driver software, and laptops can also download and install drivers from the official website of this brand.
When all USB interfaces are unavailable, it is necessary to analyze whether it is a system problem or a hardware problem. Use the startup USB flash disk to enter the PE system. If the mouse can be used in the PE system, then redo the system to solve the problem.
If it cannot be used in PE, it is a hardware problem. For desktop computers, you can try replacing the power supply, because the unstable output voltage of the power supply will lead to insufficient USB power supply on the motherboard. There may be something wrong with the USB power supply circuit of the motherboard, so we can only find a professional to repair it.
Of course, all the above are based on the premise that the USB flash disk is normal. If your USB flash disk cannot run on other computers, it is broken and can only be replaced.
