Xiaomi’s modern smartphone has long been a full-fledged handheld computer that stores gigabytes of photos, videos and documents. Sooner or later, every owner faces the need to transfer this data to the big screen for editing, backing up or quickly cleaning internal memory. Direct wired connection remains the most reliable and fastest way to solve this problem, regardless of the speed of Wi-Fi or cloud services.
However, unlike simple flash drives, Android smartphones require the right interface to communicate. By default, the device can only charge, ignoring the computer's attempts to see files. In this article, we will break down all the nuances of connection, from choosing a cable to installing specific drivers, so that you can seamlessly manage the content of your gadget.
Synchronization doesn't require a lot of technical knowledge, but attention to detail is critical. The wrong choice of port mode or the lack of the right software often causes the PC to simply not respond to the connection. We'll look at an action algorithm that's relevant to all current models, including the Redmi and POCO series.
Choosing a quality cable and checking ports
The first and most important step is the physical connection of the devices, and many users make the mistake of using cheap cables designed solely for charging, which are simplified in their interior design and lack the necessary contacts to transmit data, so the computer will not be able to detect the phone, no matter how long you wait.
Check the connectors on both devices. The USB port of your smartphone often accumulates dust and pile from your pockets, preventing close contact. Carefully clean the socket with a dry toothbrush or wooden toothpick, avoiding metal objects that can close contacts.
- 🔌 Use the original cable from the delivery kit or a certified analogue marked with data support.
- 🖥️ Connect the device directly to the ports on the motherboard (behind the system unit), bypassing the front panels and USB-hub.
- 🔍 Visually check the connectors for no oxidation, dirt or mechanical damage.
⚠️ If the phone is only charged when connected, but does not emit connection sounds and does not vibrate, in 90% of cases the problem lies in poor-quality cable.
💡
Try using a cable from another Type-C connector to prevent a wire malfunction, and often headphone or power bank cables are not suitable for data transmission.
Setting up the USB mode on a smartphone
Once connected physically, Android defaults to Charge Only for security reasons, so that the computer can see the file system, you need to manually switch the interoperability protocol, which is standard for all MIUI and HyperOS devices.
Immediately after the connection, swipe the notification curtain from top to bottom, and you will see the system notification “Charge via USB” or “Setting up USB.” Click on this line to reveal the additional menu.
To transfer files, select File Transfer (MTP) mode, which emulates the media device and allows the computer to see folders with photos, music and documents. If you only need to transfer photos, you can choose PTP mode, but MTP is the universal standard.
Path to setup: Notification curtain → Charging via USB → File transfer☑️ Connection check
Installation and update of drivers in Windows
Even with the phone’s right settings, the computer may not see the device if the operating system is missing or not working properly. Windows 10 and 11 usually automatically find the necessary components, but older OS versions or Xiaomi specific models may require manual intervention.
Open Device Manager on your computer. You can do this by right-clicking the Start button and selecting the appropriate item on the menu. In the hardware list, look for the Portable Devices section or an unknown device with a yellow exclamation mark.
If the device is displayed with an error, right-click on it and select “Update Driver.” Then select automatic search. If that doesn’t work, download the official Mi PC Suite utility or the universal Google USB Driver driver from the developer’s website.
| Type of device in the dispatcher | Status of work | Action required | Probability of success |
|---|---|---|---|
| Android Phone / MTP | It's working fine. | No action required | 100% |
| Unknown device | Code 43/Error | Install drivers manually | 85% |
| USB port (with error) | Device not running. | Reinstall USB controllers | 90% |
| ADB Interface | Demands debugging. | Enable debugging over USB | 95% |

Using USB debugging for advanced users
For those who need to do more than just copy files, but also have full control of the system, install applications, or debug code, debug mode is a tool hidden in the developer menu and gives deep access to the smartphone file system via a computer.
To activate this feature, go to the phone's settings and find "About Phone." Click on 7-10 Once in a row on the line "Version" MIUI» or "Version" OS», Until you see the message "You've become a developer," and then a new section "More" will appear in the main settings menu» → «For developers».
Inside this menu, find the USB Debugging Switch and activate it. When you first connect to a new computer, a request for debugging permission will appear on your smartphone screen. Be sure to tick the "Always Allow from this computer" box and confirm the action.
- 💻 Allows the use of tools ADB for remote command line management.
- 📂 Gives access to system folders hidden in normal mode MTP.
- 🛠️ Necessary for unlocking the bootloader and flashing the device.
⚠️ Attention: Enable debugging by USB It's a mode that provides a high level of data access that can be exploited by attackers when connecting to public charging stations.
Alternative methods of data transmission
If wired connectivity is impossible or uncomfortable for some reason, Xiaomi’s ecosystem offers several wireless alternatives that may be less fast at transferring gigabytes of data, but ideal for fast document and photo processing.
The built-in “Mi Share” (formerly Mi Drop) feature allows you to transfer files over Wi-Fi Direct at high speed. On a Windows 10/11 computer, you can use the built-in “Connect with your phone” feature or install the official Mi PC Suite app, which duplicates the functions of a wired connection over the air.
Also worth mentioning is cloud services. Sync through Google Photos or the Xiaomi Cloud is automatically in the background, which eliminates the need to think about cables, although it requires a stable Internet connection and free space in the cloud.
💡
Wireless connection via USB 3.0 provides transfer speeds of up to 400 MB/s, whereas even fast Wi-Fi 5 rarely exceeds 50-80 MB/s in real conditions.
Solving Common Connection Problems
Despite the simplicity of the procedure, users often experience situations where the computer stops seeing the phone after a system update or port change, most often solved by restarting both devices, which resets the time buffer errors.
If the phone is identified as an unknown device, try removing the driver in Device Manager completely, disabling the cable and plugging it back in again, the system will try to reinstall the component clean, and switching USB mode from MTP to PTP and back again helps.
In rare cases, the problem lies in the settings of energy saving. USB-Windows ports. Go to properties. USB-root USB-the controller in the Device Manager, the Power Management tab, and uncheck the box from the item "Allow disconnection of this device to save energy».
- 🔄 Reboot your smartphone and computer – it solves 50% of connection problems.
- 🔌 Try another one. USB-port, preferably USB 2.0 if 3.0 is not running smoothly.
- 📱 Check if the phone is enabled only charging in special features.
