How to set up USB on Xiaomi phone: the complete guide

Modern smartphones Xiaomi, Redmi and POCO They are powerful multimedia centers that often require interaction with a personal computer, and users are faced with the need to transfer large volumes of photos, videos or install system updates manually. MIUI The new HyperOS has specific security settings that limit functionality by default. USB-port.

When you first connect a cable, the device often goes into Charge Only mode, hiding files from the outside world, this is done to protect personal data from unauthorized access when using public charging stations. To unlock the full potential of the interface, you need to correctly configure the connection settings in the engineering menu or standard system settings.

In this article, we will take a look at all available USB modes, methods for activating hidden functions, and ways to fix common connection errors. You will learn how to turn your smartphone into a full-fledged drive or debugging tool.

Basic modes of operation of the USB interface

The Universal Serial Bus interface in Xiaomi smartphones supports several data exchange protocols. By default, the system chooses the most secure option, which allows you to only recharge the battery. To transfer data, the user must manually select the appropriate protocol in the notification curtain or through the engineering menu.

The most common standard is MTP (Media Transfer Protocol), which allows a computer to see the phone's file system as a media device. Unlike the old drive mode, MTP allows access to files without formatting partitions, but can run slower when copying thousands of small files.

For advanced users, PTP (Picture Transfer Protocol) mode is available, emulates a digital camera and is often used if the computer does not see the phone in MTP mode. There is also a MIDI mode for connecting musical instruments and RNDIS for distributing Internet via cable.

It is important to understand that mode choices affect not only file visibility, but also the speed and commands available, for example, to work with system partitions through ADB, it is a debugging mode that is activated separately.

Activation of File Transfer Mode (MTP)

The easiest way to get your computer to see files is to switch mode through the notification bar. After connecting the cable, lower the curtain on the top of the screen. You'll see a "Charge via USB" or similar notification. Click on it to open the mode selection menu.

In the list that opens, select File Transfer or File Transfer. The system can request permission to access the data — confirm the action. Now a new device with your smartphone name will appear in My Computer.

If the standard menu doesn’t appear or the item disappears quickly, you can use the hidden engineering menu. To do this, dial the code ##13491##. From the USB Configuration menu that opens, select Default configuration and set the MTP value.

• 📁 Regime. MTP Provides compatibility with Windows, macOS and Linux without installing drivers.
• 🔒 Security system MIUI Blocks access to files until confirmed by the user.
• ⚡ Copy speed depends on the quality of the cable and version. USB port.

Sometimes it helps to reboot the device after changing the settings, which resets temporary driver errors and force updates to the configuration. USB-controller.

💡

Use the original Xiaomi cable or a certified analogue. Cheap charging-only cables have no data lines, and no settings activate them.

Enabling USB debugging for advanced users

For developers and enthusiasts who want to install applications through ADB Or you can do full backups of the system, you need to activate debugging, and this process requires you to turn on the hidden menu "Developers." Go to Settings. → About the phone and quickly press 7 times on the item "Version" MIUI» (or "Version" OS»).

Once you have a "You've become a developer" message, go back to the main settings menu. Find "Additional" or "Extended Settings" and select "Developers" and find the "Debug by" switch. USB» and activate it.

When you connect to a debugging computer, the smartphone screen will request permission to debug from that computer. Be sure to tick "Always Allow from this computer" and click "OK." Without this confirmation, the computer will not gain access to the command line of the device.

⚠️ Attention: Including debugging by USB Never connect your phone to someone else's or public computer with activated debugging, which can lead to data theft.

The developer menu also includes the option “Select USB configuration,” where you can force mode to work if the automatic definition fails. For stable operation, ADB recommends choosing MTP or PTP.

Setting up USB-modem

Xiaomi smartphones can not only receive, but also give the Internet through cable. USB-The modem is useful when Wi-Fi is unstable and Bluetooth is too slow.

Go to Settings. → Wi-Fi hotspot (or "Connect and Sharing"). Find the item «USB-The computer recognizes the new network connection as if you had connected an Ethernet cable.

The advantage of this connection is low latency (ping) and no need for drivers, since the standard RNDIS protocol is used. However, the phone’s battery will be consumed faster due to the simultaneous operation of the communication module and data transfer.

If the paragraph USB-The modem is inactive (gray), check if the data is on the mobile network. SIM-card is not available.

Resolving problems with connecting to the computer

A common problem with Xiaomi users is that the computer sees the phone only as a charger. The first step should always be to check the cable. Many cheap cables do not have internal data contacts (Data+ and Data-), with only power lines.

The second reason may be missing drivers. While Windows 10 and 11 typically find devices automatically, older versions of the OS or specific models may require installing Mi PC Suite or Google USB Driver universal drivers.

Try replacing it. USB-Ports on the front of the system unit often have poor contact or power shortages. Connect the cable directly to the motherboard at the back. USB developer-menu.

• 🔌 Check the integrity of the Type-C connector in the phone – there often accumulates dust and pile.
• 💻 Update the drivers of your computer’s motherboard chipset.
• 🔄 Restart both devices – phone and computer – before reconnecting.

⚠️ Warning: If your computer makes a device connection sound but nothing happens, try pressing Win + R, enter devmgmt.msc and find the device with the yellow exclamation mark in the Device Manager to update the driver manually.

In rare cases, the problem lies in the software failure of the MIUI shell. Clearing the cache of the Settings application or resetting network settings can help restore the correct operation of ports.

💡

90% of problems with connecting Xiaomi to a PC are solved by replacing the cable with a high-quality analogue with support (data transfer).

Using USB OTG on Xiaomi

OTG (On-The-Go) technology allows you to connect external devices to your smartphone: flash drives, keyboards, mice and even external hard drives. In modern versions of MIUI and HyperOS, OTG support is enabled by default and does not require activation in the menu.

When you plug in a flash drive, a new partition will appear in the file manager. If that doesn't happen, check the drive file system. Android natively supports FAT32 and exFAT. The NTFS format may require third-party apps or special drivers to be installed.

To connect devices with a USB-A connector, you will need an adapter or hub. When connecting energy-intensive devices such as HDD, the smartphone may not produce enough current, so it is recommended to use an externally powered hub.

Disable the devices OTG You need to use the software menu, and the notification curtain will have an icon. USB-Devices – click on it and select “Disable” USB-drive. Abrupt extraction can lead to data loss.
