Modern Xiaomi and Redmi smartphones have a huge amount of internal memory, but when working with large amounts of data often requires direct connection to the computer. By default, many devices after connecting the cable go into charging mode only, which protects data from unauthorized access, but prevents the user from quickly copying photos or documents. To change this setting, you need to manually activate the appropriate mode in the MIUI or HyperOS system.
In this article, we will discuss in detail all the nuances of the setting USB-From basic actions in the notification curtain to hidden engineering menus, the right setup will allow you not only to transfer files, but also to use the phone as a modem or audio source for the PC. Ignoring these settings can cause the computer to see the device but not gain access to the file system.
Basic setting through the notification curtain
The easiest and most common way to switch the mode of operation USB-The port is available immediately after the cable is physically connected. When you connect the Xiaomi smartphone to the computer, the system automatically selects Safe Charge Only mode. To change this, lower the notification curtain from top to bottom. You will see the system notification about the connection. USB, which is usually hidden by default or displayed as "Charging through" USB».
Click on this notification to deploy the hidden settings menu, and you will see a list of available interface modes. Here, you need to select the option File Transfer (sometimes marked as File Transfer). MTP — Media Transfer Protocol: This mode allows the computer to display internal memory and SD-Smartphone card as external drive. If you select "Send photo" mode» (PTP), The computer will only see folders with images, which limits the functionality.
💡
If the connection notification does not appear immediately, try unlocking the smartphone screen – on a locked device, the system can hide security dialog boxes.
It's worth noting that some versions of the MIUI shell may have slightly different interfaces, but the logic remains the same: After selecting File Transfer mode, a beep should appear on the computer screen and a new drive will appear in My Computer, and if that doesn't happen, it may be the cable itself that only supports charging, or the absence of drivers on the PC.
Using USB Debugging Mode for Advanced Users
For those who do not have standard methods or if the file transfer mode is not activated automatically, there is a deeper level of settings. USB — It's a developer tool that allows a computer to have full access to the Android system, and enabling this feature often helps wake up the computer» USB-port and get the computer to correctly identify the device. → About the phone and seven times quickly click on the version MIUI.
After the message “You became a developer” appears, go back to the main settings menu and go to Advanced Settings. → For developers, find the item "Debugging by USB» And activate it. When you connect the debugging cable, you'll see a confirmation request on your smartphone screen. RSA-Without the confirmation of this request on the phone screen, the data transfer will not begin, even if the mode is not MTP chosen.
☑️ Checking the debugging regime
Using debugging mode also allows you to use specialized file management software such as ADB (Android Debug Bridge), which allows you to not only copy files, but also install applications, do full system backups and perform other complex operations. However, remember that having debugging enabled on a lost device can make it easier for attackers to access your data, so in everyday use this feature is better kept off.
Default setting and constant mode selection
A common problem for users is that after each cable reconnection, you have to re-select the file transfer mode. Fortunately, you can set the default action on the developer menu. Find the default USB configuration and select File Transfer. Now, every time you connect to a familiar computer, the phone will try to go straight to the drive mode.
But Android security can ignore this setting if you connect to a new PC, and then you'll always see a request on the screen, and it's normal behavior to protect your data in public places, like when charging at the airport, and if you're confident in your computer's security, you can allow access forever by ticking the "Always Allow from this computer" box.
Why is the USB setting resetting?
It is also worth paying attention to the item “Mode” USB». In some firmware, it may be hidden or called something else. MIDI or RNDIS (USB-modem), if your goal is to work with files. Correctly configuring this parameter will eliminate the need for constant switching in the notification curtain.
Solving problems with drivers and cable
If the software settings are correct, but the computer still can't see Xiaomi, the problem may be hardware or there are no drivers. Check the cable first. Many cheap cables that come with power-bank or other devices are charging and have no data lines. Use the original cable or quality analogue labeled data.
The second important aspect is drivers. Windows 10 and 11 usually automatically install the necessary components, but sometimes this process is not correct. You can manually update the driver through Device Manager. Find a device with an exclamation mark or Portable Devices section, right click and select Update Driver → Search for drivers on this computer → Select a driver from the list of available drivers on your computer.

|---|---|---|
| The phone is just charging. | Not selected MTP mode | Select "File Transfer" in the curtain |
| The computer makes sound, but the device is not visible | There are no drivers. | Install Mi PC Suite or update manually |
| Connection is constantly broken | The cable or port is damaged. | Replace the cable, clean the USB-C port |
| Errors in copying files | File system is damaged | Check the disk for errors through the Explorer |
💡
The quality of the cable directly affects the data rate and connection stability – a bad cable can cause read errors even with the right settings.
