Connecting a smartphone to a personal computer remains one of the fastest and most reliable ways to transfer large amounts of data. Despite the development of cloud services and wireless technologies, it is the cable method that guarantees stable speed without the risk of interruption. Xiaomi, like other Android-based manufacturers, provides users with several options for interacting with the file system through the use of the file system. USB-port.
Many users are faced with a situation where, after connecting the cable, the computer emits a characteristic sound, but the folders with the files do not appear. This is a normal phenomenon due to the security policy of the operating system, which by default blocks access to data. To change this setting, you need to perform a few simple actions in the interface of the device.
In this guide, we will take a look at all the steps of connecting, from choosing the right cable to activating hidden debugging functions. You will learn how to properly configure file transfer mode and what to do if the system does not see the device. The correct port configuration will allow you not only to copy photos and videos, but also to use the phone as a modem or development tool.
Equipment preparation and cable inspection
The first step to a successful connection is to physically check the components. Often the problem lies not in the software settings, but in the cable itself, which can be designed solely for charging. Cables bundled with cheap power banks or accessories often have only two internal contacts to power, ignoring data lines.
Carefully inspect the connectors for dust, pile or oxidation that can prevent tight contact. To connect Xiaomi smartphones with USB Type-C interface, it is recommended to use USB 3.0 cables or higher if your laptop maintains the appropriate speeds, although a quality USB 2.0 is enough for basic file transfer.
- 🔌 Use the original cable from the supply kit, as it is guaranteed to support data transfer protocols.
- 💻 Connect the device directly to ports on the laptop motherboard, avoiding use USB-hubs without their own food.
- 🧹 Check the phone's charging socket for contaminants by gently removing dust with compressed air or a dry soft brush.
⚠️ Warning: Using damaged or too long cables (more than 2 meters) can cause a voltage drop and an unstable connection where the device will constantly reconnect.
Configure USB mode in the MIUI interface
Once the device is physically connected to the computer, the MIUI operating system defaults to Charge Only mode, which is designed to protect user data from unauthorized access when connecting to public charging stations or other computers.
Unlock your smartphone screen and lower the notification curtain from top to bottom, and you'll see a system notification with text like "Charge through" USB» or "Click for other actions." Tap this message to open the mode selection menu. USB-Interface. Here you need to select the option File Transfer (MTP), This allows the computer to see the internal memory and SD-map.
Sometimes the system may request permission to access data, a dialog box will appear on the smartphone screen asking about trust in this computer, be sure to click "Allow" or "Always Allow" so that in the future the connection will happen automatically without unnecessary confirmation, if you do not, the computer will see the device only as a source of power.
☑️ Connection check
It’s worth noting that in some versions of HyperOS firmware or newer MIUI shells, the menu may look a little different, but the logic remains the same. If you don’t see the notifications right away, try turning off and reconnect the cable while keeping the screen on. You can also go to Settings → Connected Devices → USB if that option is available in your version of the software.
Installation of drivers and work with the conductor
Modern Windows 10 and Windows 11 operating systems usually automatically find and install the necessary drivers for Xiaomi devices. However, in some cases, especially on older versions of Windows or using specific models, it may be necessary to manually install drivers. Without the correct driver, the computer will not be able to correctly interpret the signals coming from the smartphone.
If you see an unknown device with a yellow exclamation point in the Device Manager, it is recommended to install the official Mi PC Suite utility or universal ADB drivers. Often it is enough to just wait a few minutes after connecting until the system completes the background installation of components.
After successfully installing drivers in My Computer, new drives will be available that match the phone’s internal memory and memory card. You can now drag and drop files, create folders, and manage content just like you would with a regular flash drive. For stable operation, it is recommended to use a file manager with support for long file names.

|---|---|---|
| Just charging. | Access to files is prohibited, there is only power supply | When charging in public places |
| File Transfer (MTP) | Full access to media files and documents | To copy photos, videos, music |
| Photo transfer (PTP) | Emulation of a digital camera for importing photos | For older PCs without MTP support |
| USB-modem | Distribution of the Internet from phone to PC | Without Wi-Fi on your laptop |
Use of debugging mode via USB
Advanced users, developers, or deep system diagnostics may need to enable debugging mode, which allows the computer to send commands to the device, install applications directly, and access system logs, and activating this feature requires unlocking the developer menu.
To get into the hidden menu, go to Settings → About the phone and find the line "Version" MIUI» or "Version" OS». You need to press this line quickly. 7-10 Once in a row, until the message "You became a developer" appears, and then a new item "For developers" will appear in the menu "Additional" or "Extended settings».
Inside this menu, find the Debugging Switch on USB And you activate it. You'll be alerted to security risks, you'll confirm the action. When you first connect to a new computer, you'll see a request for debugging confirmation on your screen. RSA-Make sure you connect to a trusted PC and click OK».
- 🛠 Debugging mode is necessary for working with tools ADB and Fastboot.
- 🔒 Do not leave debugging on permanently unless you use it to reduce the risk of hacking.
