Chuangxiang wireless keyboard and mouse can't be used, don't say anything about the driver, there is no problem with the driver wizard detection.

The frequency of wireless keyboard and mouse is only the frequency between the keyboard and mouse itself and the receiver, which has nothing to do with the user's computer, so you don't have to pay attention to it. Is your receiver plugged into the u-port? Is there poor contact at U-port? You can try another device, such as a USB flash drive, to see if there will be continuous prompts for pulling out and inserting the device. You can try again by changing the u-port. Poor grounding of the computer and charged shell can also lead to peripheral failure. You can also check it. Keep asking if you have any questions.
