Xiaomi Poco X3 is one of the most popular smartphones in the budget segment, but its connection to the PC often raises questions among users. The device is not defined as a drive, drivers refuse to install, the files simply do not copy. In this article, we will analyze all the current ways of connecting Poco X3 to a computer (Windows, macOS, Linux), and also solve typical problems โ from the MTP USB Device Failed error to the lack of response to the connection.
It is important to understand that the method of connection depends on the purpose: whether you just need to copy a photo, manage files through the explorer, debug the application (ADB) Or even use your smartphone as a webcam, and we'll look at all the scenarios, from the basic one. MTP-The system is designed to include advanced tools like Mi. PC Suite and scrcpy for screen mirroring.
We will focus on the driver issues that arise on Windows 10/11, as well as the nuances of working with macOS (which often requires additional software).If your Poco X3 stubbornly does not want to be "friends" with your computer, at the end of the article there is a section with diagnostics and solutions for 90% of cases.
1. Connection via USB (MTP, PTP, MIDI)
The most obvious way is to use a USB Type-C cable that comes with a smartphone, but even here there are pitfalls: not every cable supports data transfer (some only charging), and the Poco X3 itself may not activate file transfer mode by default.
Step-by-step:
- Connect your smartphone to your PC with the original cable (or certified USB 2.0/3.0 with data support).
- The Poco X3 will show a notification, "Charge via USB."
- Select a mode: ๐ File transfer (MTP) โ memory-like; ๐ท Transmission of photo (PTP) โ if MTP It doesnโt work (often helps on macOS); ๐ต MIDI โ Connecting Music Controllers; ๐ Charging only โ disables data transfer.
On the PC, a conductor window with smartphone folders will open (if the drivers are installed correctly).

If an empty folder or an error "Device not recognized" appears in Windows Explorer after you connect, the problem is 95% MTP drivers.
2. Wi-Fi connection (without cable)
If USB-The port on your smartphone or PC is broken, or you just want to get rid of the wires, you can use wireless connectivity:
Method 1: Mi Drop application (for file transfer)
Mi Drop is a proprietary solution from Xiaomi, which allows you to share files between devices on the same Wi-Fi network. the transfer speed is lower than USB (about 5-10 MB / s), but for photos and documents this is enough.
How to use:
- Install Mi Drop from Google Play (if removed).
- Open the app on your smartphone and select โSendโ or โReceiveโ.
- On PC, open the address in the browser ftp://[IP-address of your Poco X3] (It's gonna be Mi Drop).
- Log in (login / password is displayed in the application) and drag and drop files.
Method 2: FTP-server ES Conductor
A more universal method is to run FTP-It's a server right on your smartphone:
- Install ES Explorer (or any other file manager with FTP).
- In the application menu, find โNetworkโ โ โFTPโ and turn on the server.
- Remember the address of the form ftp://192.168.x.x:3721.
- On PC, connect through the Explorer โ This computer โ Connecting a network disk or any FTP-client (e.g. FileZilla).

โ ๏ธ Note: When transferring large files (video, archives) over Wi-Fi, the smartphone may overheat. โ Battery status.
3. Debugging Connection (ADB and Fastboot)
If youโre a developer, testing firmware, or need low-level access to Poco X3, youโll need to enable USB Debugging (ADB) mode, which is also useful for unlocking the bootloader or restoring bricks.
Activation of ADB:
- Go to Settings โ About phone and tap on the MIUI version 7 times to unlock the Developer Settings.
- Go back to the main settings menu and find a new section for developers.
- Turn it on: ๐ง "Debugging by USB"; ๐ "Unlocking OEM" (if you plan to firmware); ๐ "Unlocking the bootloader" (to unlock the bootloader).
Connect your smartphone to your PC and confirm the debugging permission on the Poco X3 screen.
To work with ADB on PC:
- Download the Google Platform Tools.
- Unpack the archive and open the command prompt in this folder (Shift + right mouse button โ โOpen PowerShell window hereโ).
- Check the connection command: adb devices If the device is displayed โ everything works.
What if the ADB canโt see the device?
4.Use Poco X3 as a webcam or microphone
With the release of Windows 10 version 2004, there was built-in support for using Android smartphones as webcams via USB. For Poco X3, this works without additional applications, but with some nuances.
Instructions for Windows:
- Connect your smartphone to your PC in the file transfer (MTP) mode.
- Open the Camera app on Windows.
- In the list of devices, select Poco X3 (may appear as "MI POCO X3" or "USB Video Device").
For macOS/Linux, you will need the DroidCam app:
- Install DroidCam on your smartphone from Google Play.
- Download the client for PC from the official website.
- Connect via USB or Wi-Fi (in the application settings).
Typical errors and decisions:
| Mistake. | Reason. | Decision |
|---|---|---|
| MTP USB Device Failed | There are no MTP drivers | Install the MTP driver from the Microsoft Store |
| Device not identified (code 43) | Driver conflict | Remove the device in Device Manager โ โUpdate Configurationโ |
| Empty folder in the conductor | Failure MTP-protocol | Switch to PTP or restart your smartphone |
| ADB does not see the device | Lack of rights or drivers | Install Google USB Driver |
For Windows 10/11, manual driver installation often helps:
- Open Device Manager (Win + X โ Device Manager).
- Find Poco X3 under "Portable Devices" or "Other Devices" (with an exclamation point).
- Right-click โ โUpdate driverโ โ โPerform search on this computerโ.
- Select "MTP USB Device" from the list.
๐ก
If MTP drivers are not installed, try connecting your smartphone to another PC (like Windows 7). Often, the system automatically downloads the desired drivers, after which the device starts working on the main computer.
6. Alternative programs for controlling Poco X3 from PC
If standard methods are not satisfied, you can use specialized software for deep integration of the smartphone and computer.
Mi PC Suite (official software from Xiaomi)
It allows you to manage files, install applications, backup and update firmware. Minus: it runs unstable on new versions of Windows and often "does not see" the device.
- ๐ฅ Download Mi PC Suite (official website).
- ๐ง Requires the activated debugging mode USB.
- ๐ซ MacOS doesnโt work, only Windows.
scrcpy (screen mirroring + control)
A free, open source utility that displays the Poco X3 screen on a PC and allows you to control it from the keyboard/mouse. Supports screen recording and file transfer via drag-and-drop.
How to set up:
- Download scrcpy and unpack.
- Connect your smartphone in ADB mode (see Section 3).
- Run scrcpy.exe (for Windows) or./scrcpy (for macOS/Linux).
๐ก
Scrcpy works without root rights and requires no additional apps to be installed on your smartphone, and itโs the most reliable way to manage Poco X3 from your PC if you need more than just file transfers.
Airdroid (remote control)
It allows you to control your smartphone through a browser or desktop application, supports file transfers, SMS, notifications and even calls, minus: requires registration and pays for premium functions.
7. Connection to macOS and Linux
On macOS and Linux, Poco X3 connectivity is often fraught with problems due to the lack of native MTP support.
For macOS:
The system doesn't recognize. MTP-Out of the box devices. Install one of the drivers:
- ๐ Android File Transfer (official software from Google, but often bugs);
- ๐ฅ๏ธ OpenMTP (alternative to support new versions of macOS);
- ๐ MacDroid (Payable, but Most Stable Solution).
If the files are not copied, try:
- Switch the mode on the smartphone from MTP to PTP.
- Connect via FTP (see Section 2).
For Linux (Ubuntu/Debian):
Most distributions already have MTP support, but may require package installation:
sudo apt install mtp-tools mtpfs gvfs-mtpIf the device is not mounted:
- Open the terminal and check the connection: lsusb | grep Xiaomi
- Manually mounted: mtpfs -o allow_other /media/PocoX3
โ ๏ธ Note: On Linux, some file managers (such as Nautilus) may not display files with Cyrillic names correctly.
