Frequent plugging and unplugging of USB devices, or unplugging the USB device while it is transmitting data, can easily cause the instantaneous current of the USB interface to be too large, resulting in an error. If you always pay attention to safely unmounting USB devices, there will be no problems.

2. Confirm that the USB driver is installed correctly.

3. USB-IF stipulates that the power supply provided by the USB port is 5V/500mA, but currently many peripherals require power exceeding this standard. Especially for devices such as external hard disk boxes or mobile hard disks, this situation can easily occur during use. Sometimes using a USB extension cable or using multiple USB devices at the same time may also cause insufficient USB power supply.

3) USB hard disk enclosure powered by dual USB plugs.

4) Do not use USB extension cable.

5) USB devices should be plugged into the USB interface on the back of the machine to avoid signal attenuation.
