Method:

1. Open "Device Manager" and find the device that cannot be connected (usually your own Huawei mobile phone).

2. Click the right mouse button on it, select "Update Driver Software" in the pop-up menu, and click "Browse Computer to Find Driver Software" in the pop-up menu.

3. Then continue to click "Select from the device driver list of the computer".

4. Then find "Portable Device" in the pop-up list, select it and click "Next".

5. Then select (standard MTP equipment)->-> in the pop-up menu; MTP USB device. Then click Next. Select Yes in the warning window that pops up.

6. After installation, your mobile phone will be displayed here. So it can be used normally.

7. Matters needing attention

You need to turn on USB debugging mode on your mobile phone first, so as not to connect and see the content after updating the driver.

The USB port installed in the mobile phone driver can only recognize this USB port. If another USB port is used to connect the mobile phone, the above work needs to be repeated. If you take the trouble to connect every USB port, you can use it directly no matter which port your phone is plugged into in the future.
