In this article, we will take a look at all the steps of connecting, from choosing the right cable to installing specialized drivers. You will learn how to switch your smartphone to drive mode, activate USB debugging and use ADB tools for advanced management. Competent configuration will not only allow you to quickly copy files, but also access the system functions of the device.
Follow our guidelines to ensure a stable connection between your gadget and your PC. We will look at common problems that users face and propose specific solutions for each of them. The connection process will become simple and understandable if you know which switches to activate in the developer menu.
Choosing a quality cable and checking ports
The first and most critical step is choosing a physical connection. Many users mistakenly believe that any micro-USB cable is suitable for data transfer, but this is not the case. Cheap cables are often designed solely for charging and have no internal conductors to transmit information. Using such a cord will only display the charge icon on the smartphone screen, but the computer will not see the connected device.
Carefully inspect the cables you have. The original or certified accessory from well-known brands is the best choice for working with the Xiaomi Mi A1. If the cable is damaged, rubbed or has visible insulation defects, its use can lead to unstable connection or even short circuit. The integrity of the contacts inside the micro-USB connector also plays an important role, since this connector is subject to wear.
⚠️ Warning: Avoid using damaged cables or ports USB, This can cause power surges and damage to your smartphone's power controller.
It is also worth checking for yourself. USB-It is recommended to connect the smartphone directly to the ports on the motherboard (at the back of the system unit), rather than to the front panel or USB-Hub, ports USB 3.0 (usually blue) provides a higher data rate than the USB 2.0, though Xiaomi Mi A1 However, power stability in 3.0 ports is often higher.
- 🔌 Use only the original micro-USB cable, which comes with the kit, or its quality counterpart.
- 💻 Connect the device directly to the ports on the back of the computer to eliminate power problems.
- 👀 Visually inspect the connectors for dust, oxidation, or physical damage before connecting.
- 🔄 Try replacing the cable if the computer makes the connection sound, but the device is not defined.
Configuring USB mode in the Android system
Once you physically connect your smartphone to your computer, the Android operating system defaults to Charge Only, a standard security measure that prevents unauthorized access to data when you connect to public charging stations. To make your computer see the files, you need to manually change this setting. A USB notification appears in the notification curtain immediately after you connect.
Lower the top menu curtain and find the “Charge via USB” or “USB Settings” notification. Click on it to reveal the list of available modes. Select the “File Transfer” (MTP) option to transfer files. In this mode, the Xiaomi Mi A1 will be defined by the computer as an external drive, and the device icon will appear in “My Computer.” MTP mode is the standard for modern Android smartphones.
If you want to send photos from the camera, you can choose PTP (Picture Transfer Protocol) mode, in which case the computer will see the smartphone as a digital camera, which can be useful for older operating systems or specific software for photo processing that does not work with MTP. However, for ordinary copying of folders and documents, this mode is less convenient.
☑️ Checking settings USB
Sometimes the system may not offer a choice of mode immediately, in which case try to unlock the screen of the smartphone after connecting the cable. If the screen is locked, Android may deny access to data for security reasons. Unlocking the device is often the trigger for a request for permission to access files.
Installation of drivers for Windows
Windows 10 and 11 usually automatically finds and installs the drivers you need for the Xiaomi Mi A1. However, in some cases, especially on older versions of Windows (7, 8) or using stripped-down OS builds, the automatic installation may not work.
To solve this problem, you can use the built-in Windows tools. Open Device Manager, find a device with a yellow exclamation point, right-click and select "Update driver." Then, select "Do a driver search on this computer" and select from the list of drivers already installed. USB-device MTP. Choosing the right driver from the list often solves the problem without downloading unnecessary files.
| Type of device | Required driver | Source | Status of installation |
|---|---|---|---|
| Xiaomi Mi A1 (MTP) | MTP USB Device | System (Windows) | Automatically. |
| Xiaomi Mi A1 (ADB) | Android ADB Interface | Android SDK / Xiaomi | Manually. |
| Xiaomi Mi A1 (Charge) | Systemic | Automatically. | |
| Unknown device | Depends on the equipment ID | Search required | Mistake. |
If standard methods do not help, it is recommended to download the official Mi PC Suite utility or universal Google USB Driver drivers. Installing drivers from the manufacturer guarantees the correct operation of all functions, including contact synchronization and backup. Universal ADB drivers can also be installed separately for advanced users.
⚠️ Warning: Do not download drivers from unverified aggregator sites. Use only official sources or built-in Windows registries to avoid installing malware.
Activation of the developer mode and debugging via USB
For deeper interactions with the computer, such as using ADB (Android Debug Bridge) debugging tools, you need to activate the hidden developer menu. By default, it is hidden from the average user to prevent accidental changes in critical system settings. Debugging mode opens up a wide range of options for managing the smartphone.
To activate the menu, go to Settings → About the phone. Find the line "Version." MIUI» (In the case of Android One, this will be “Build Number” and click on it quickly. 7-10 After a few clicks, the counter will appear, and then the message "You became a developer!". Then in the main settings menu, in the section "Advanced settings" or "System", a new item will appear For developers.
Path to the menu: Settings → System → For developers → Debugging by USBInside the developer menu, find the USB Debugging Switch and activate it. The system will issue a security risk alert -- confirm the action. Now, when you connect the Xiaomi Mi A1

Why do you need USB debugging?
Using ADB and Fastboot for advanced users
ADB (Android Debug Bridge) is a powerful tool in the enthusiasts’ arsenal. It lets you send commands to your smartphone directly from the computer’s command line. This is useful if the touch screen doesn’t work but the phone turns on, or if you need to remove system applications that can’t be removed in the usual way. Xiaomi Mi A1 is great for working with ADB due to its proximity to Android stock.
To do this, you'll need a suite of Google's Platform Tools. After unpacking the archive, open the command line in the tool folder and type in the link check command:
adb devicesIf debugging is enabled correctly, you will see a list of connected devices with a serial number and device status. If unauthorized, look at the phone screen and confirm access. To enter the Fastboot mode, which is used to flash or unlock the bootloader, use the command:
adb reboot bootloader- 📱 Adb shell command opens interactive shell to execute commands inside Android.
- 💾 Adb pull team /sdcard/photo.jpg c:/ Allows you to copy a file from your phone to your PC.
- 🔄 Adb reboot command performs soft reboot of device.
- 🛠 The team of fastboot devices checks the connection in bootloader mode.
Fastboot mode is also available when you turn on your phone with the volume button pressed, and in this mode, your computer sees a device with an Android Bootloader Interface ID. It's a low-level mode that allows you to change partitions. Beware: the wrong commands in Fastboot mode can turn your phone into a brick.
💡
Use the command "adb kill-server" and then "adb start-server" if the computer stopped seeing the connected device with debugging enabled. This restarts the ADB demon on the PC.
Solving Common Connection Problems
Even if you follow all the instructions, you can get complicated. One of the common problems is that the computer sees the phone but doesn't show the folder. This is often solved by reconnecting the cable after selecting the MTP mode or rebooting both devices. Driver conflicts can also interfere with normal operation, especially if other Android smartphones have previously connected.
If your computer doesn’t respond to the connection at all, check if the phone has “Charge Only” on the menu. USB (If you have this option in your firmware version, it is also worth checking the energy saving settings. USB-Windows ports. Device Manager, root properties USB-You can check the box from the item "Allow disconnect this device to save energy." Xiaomi Mi A1 It may require a stable power supply that the system is trying to save.
⚠️ Warning: If the phone gets hot while connecting to a PC or makes strange noises, turn off the cable immediately.
In rare cases, the problem lies in an antivirus or firewall that blocks an unknown device. Try temporarily disabling the security software. Also make sure that the phone does not have a restriction on connecting only to familiar computers (the “Only familiar PCs” feature in USB settings, if it is available in your Android One build). Resetting network settings on your smartphone sometimes helps restore the correct operation of communication protocols.
