Connecting a Xiaomi, Redmi or POCO smartphone to a computer seems like a simple task β until you encounter errors like βDevice not recognizedβ or lack of access to files. The reasons may lie in the wrong settings of the phone, outdated drivers on the PC or even in the locking by MIUI. In this article, we will analyze all the current ways of connecting (including hidden MIUI functions), and also solve typical problems that users face.
Feature of Xiaomi devices - branded shell MIUI, which often blocks the connection to USB For example, when you first connect to a new PC, the phone may request confirmation via Settings. β Connection to USB, In addition, some models (such as Xiaomi 13 Pro or Redmi Note 12) require additional configuration of the data transfer mode. MTP-mode, but also alternative methods: Wi-Fi (FTP), ADB, and also proprietary Mi Assistant software for deep synchronization.
Important: If you plug your phone in for firmware or debugging, youβll need Qualcomm or MediaTek drivers (depending on the processor), and their absence is a common cause of failures when working with tools like the Mi Flash Tool or Fastboot. At the end of the article, youβll find a driver compatibility table for popular Xiaomi models.
1. USB Connection: Step-by-step instruction for MIUI
The most common way is to use a USB-Type C cable (or Micro-USB for older models), but even here there are nuances: Xiaomi can block file transfers by default if you don't turn on a special mode. Here's how to do it correctly:
1. Connect your phone to your PC using the original cable (cheap analogues often donβt support data transfer).
2. On the phone screen, a charging notification via USB will appear - tap it.
3. In the menu that opens, select File Transfer (MTP). If this is not the case, go to Settings β Connected Devices β USB and activate the mode manually.

Alternative USB Modes: What Do You Mean and When to Use
When connecting to a PC, Xiaomi offers several modes of operation, their choice depends on your task:
| Regime. | Description | When to use |
|---|---|---|
| File Transfer (MTP) | Standard protocol for sharing media files and documents. | Copying photos, music, videos on PC. |
| Image Transmission (PTP) | Optimized for photos, but slower than MTP. | If MTP doesnβt work or you need compatibility with older PCs. |
| USB-modem | Turns the phone into a source of internet for PCs. | To distribute mobile traffic (an alternative to Wi-Fi hotspot). |
| Charging. | Only power, no data transmission. | If you need to charge your phone quickly without connecting to a PC. |
| Midlink (Mi Assistant) | The proprietary mode for synchronization with Mi PC Suite software. | For backup, firmware updates or SMS management. |
On models with MIUI 14+, File Transfer can automatically shut down after 10 minutes of inactivity, which is a power saving feature. To turn it off, go to Settings β Battery β Power Saving Modes and deactivate the option βLimit USB at Downtimeβ.
If you need to connect to your phone for debugging (for example, to install custom firmware), select Debugging over USB.
- Open the settings β About the phone β version of MIUI.
- Tap the version number 7 times until the notice βYou became a developerβ appears.
- Back to Settings β Additionally. β For developers.
- Turn on USB debugging and confirm the permission.

3. Installation of drivers for Xiaomi on Windows
A common problem with connecting is the lack of drivers. Windows 10/11 usually installs them automatically, but to work properly (especially with ADB or Fastboot) requires specialized drivers.
1. Download the official driver package from the Xiaomi website:
For Qualcomm: Mi Flash Tool processors (includes drivers).
For MediaTek processors: MTK Drivers.
2. Connect your phone to your PC in Fastboot mode (turn off your phone, then press Volume Down + Power).
3. In Device Manager (Win + X β Device Manager), find a device with a yellow exclamation point (usually Android or Xiaomi).
4. Right-click β Update the driver β Search for drivers on this computer and specify the path to the downloaded files.
β οΈ Warning: If the phone is still undetectable after installing the drivers, check the digital signature of the drivers. 11 You may need to disable signature verification: - Run the command prompt on behalf of the administrator. - Enter: bcdedit /set nointegritychecks on - Restart your PC. After installing the drivers, return the settings back to: bcdedit /set nointegritychecks off
To simplify the process, you can use the Xiaomi utility ADB/Fastboot Tools, which automatically installs the necessary drivers and offers a graphical interface to work with the phone.
