1, there is dust at the USB port. Because the USB interface on the little daren's point-reading pen is not covered, dust can be encountered in daily use. When the little daren can't connect to the computer, you can try to take a thinner cotton swab and gently wipe the inside of the usb interface.

2. Use the original data cable. Although the miniUSB interface of the little daren point-reading pen is similar to the data cable of the Android phone, not all Android data cables support the data transmission of the malt little daren point-reading pen. Please try to use the original data cable of Little Daren point reading pen.

3. The USB interface is not in good contact. Little daren's point reading pen has green and red indicator lights. Red light for charging and green light for data. After confirming that there is nothing wrong with the data cable, you can try to gently shake the two ends of the data cable linking the computer and the little daren point-reading pen. Sometimes the poor connection of the data cable will also lead to the failure of the little talent's point reading pen to connect with the computer.

4. The computer does not support this hardware. When you encounter this problem, please try to restart the computer first. If there is still a problem, please try to replace the computer.

5. You can also try to use a sharp object, press the reset button "reset" on the back of Little Daren's point-reading pen, and then try to connect with the computer after about 3-5 seconds.
