Modern Xiaomi smartphones running on the Android operating system have a wide functionality that is often hidden from the eyes of the average user. USB-Standardly, the gadget offers only basic options like charging or transferring files, but for developers and enthusiasts this is not enough.
Change of configuration USB-Interface can be required in various situations: from the need to debug applications and firmware of the device to trying to bypass software restrictions when connecting to specific hardware. Understanding how to manage these parameters gives you complete control over your device’s physical port.
In this article, we will take a closer look at all the available methods to change the USB mode on Xiaomi, including the use of hidden developer settings, ADB commands and specialized utilities.
Why you should change USB mode on Android
The standard way a smartphone will behave when it connects to a computer is to charge a battery, and it's done for safety and energy efficiency, but if you plan to transfer large amounts of data, use your phone as an external modem, or debug your code, you'll need to change the protocol of interaction, and without switching to MTP (Media Transfer Protocol) mode, the computer will simply not see the device's file system.
USB debugging is critical for developers, allowing them to install applications directly from the PC, access system logs in real time, and execute complex scripts, and there are more specific modes, such as RNDIS for emulating a network adapter or MIDI for connecting musical instruments, which are hidden in the standard interface.
It is important to understand that misconfiguring these settings can cause the computer to stop recognizing the device or the charging becomes unstable, so before making changes to the system settings, you need to clearly understand what kind of result you want to get.
💡
Always check integrity USB-cables before changing settings, as cables often only support charging mode and do not transmit data.
Activate the developer menu on Xiaomi
The first and mandatory step to access the advanced USB settings is to activate the hidden “Developers” section, which has its own features in the MIUI shell compared to stock Android, you need to open the “Settings” app and go to the “About Phone” section.
Find the line "Version" MIUI» You can start to quickly press your finger, and it usually takes 5 to 7 quick taps, and once the system realizes that you're trying to activate a hidden feature, a pop-up notification will appear that you've become a developer. After that, in the main menu of settings, in the section "Additional", a new item will appear.
When you log in to the Developer Menu, scroll down to the Debugging Block. This is where all the switches are located. By default, USB Debugging is turned off for security purposes. Activate it by confirming action in the warning pop-up window.
☑️ Activation of the developer mode
⚠️ Attention: Activation of debugging by USB Do not connect your smartphone to public charging stations or unfamiliar computers with debugging enabled, as this creates a potential vulnerability to data.
Basic USB connection modes
Once debugging is enabled, the standard USB mode selection menu becomes more informative, but still limited. When connecting the cable to the PC, the notification suggests choosing one of the options. Charging Only mode limits current and blocks data transmission, which is useful for storing charge in public places.
Mode “Transfer of files» (MTP) It's a standard for multimedia, and it allows the computer to see the internal memory and SD-But unlike the storage mode, it's like a network storage (UMS), which was used in older versions of Android, MTP It does not allow partition formatting or low-level file system management without special permissions.
There is also a PTP (Picture Transfer Protocol) mode that emulates a digital camera, which is rarely used, mainly for older cameras or specific software that can not work with MTP. The right mode depends on what equipment or program you interact with.
Use of Engineering Menu and ADB Teams
To access hidden modes like MIDI, RNDIS, or forced charging, you will need to use the ADB command line, a powerful tool that allows you to send commands directly to the operating system, and you first need to install the Platform Tools package on your computer.
Connect your smartphone to your PC, make sure that the debugging confirmation appears on the phone screen, and open the terminal. USB-The configuration command is used by adb shell getprop sys.usb.config. It will show the currently active set of protocols.
To change mode, a property setup command is used, for example, to switch to RNDIS mode (network card), the command will look like this:
adb shell setprop sys.usb.config rndis,adbAfter the command is executed, the device can disconnect and reconnect with the new identifier.
List of available configurations
Comparison of data transmission protocols
Different USB port modes involve different transmission speeds and access levels, and understanding these differences will help avoid errors when connecting external devices or trying to flash your phone. Below is a table comparing the main characteristics of popular modes.
| Regime. | Speed. | Access to files | Charging. |
|---|---|---|---|
| Charge Only | No. | No. | Complete. |
| MTP | High (USB 2.0/3.0) | Reading/Recording | Yes. |
| PTP | Medium | Photo/video only | Yes. |
| RNDIS | Depends on the network. | No (network) | Yes. |
Regime. RNDIS It is often used to distribute the Internet through USB, When the Wi-Fi module is faulty or requires the most stable connection without loss of packets. MTP It is not an option for a user who wants to copy a movie or music.
It is worth noting that the MTP transfer speed on Xiaomi can vary depending on the type of file system. If the internal memory is formatted in ext4 and the computer is running Windows, MTP drivers can run slower than when using exFAT on external drives.
💡
For maximum transfer speed of large files (more than 10 GB), use the original cable. USB 3.0 and port USB 3.0 on the computer, avoiding USB-hubs.
Solving Connection and Driver Problems
Often, users are faced with a situation where the phone is charging, but the computer does not see the device in any of the modes. 90% of the time the problem lies in the lack of necessary drivers or using a cable that supports only charging. On Windows 10 and 11, drivers are usually installed automatically, but older versions of the OS may require manual installation of Google USB Driver or Mi USB Driver.
If an unknown device with an exclamation point appears in the Device Manager, try updating the driver manually by specifying the path to the ADB driver folder. Also, switching the USB mode in the notification immediately after connecting while the system identifies the device.
In some cases, resetting USB settings helps. To do this, in the For Developers menu, find the option “Selecting a USB configuration by default” and select the desired value. If the problem persists, check the physical port of the smartphone for dust or contact oxidation, as this is a common cause of unstable work.
⚠️ Warning: Never turn off the cable USB during active data transmission or firmware of the device, this can cause damage to the file system or software failure of the bootloader.
