How to turn on USB in Xiaomi: The Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones often face the need to expand the functionality of their device by connecting external drives, game controllers or peripherals. MIUI or a new HyperOS sometimes hides the important settings needed to communicate correctly. USB-Connection is the key to fully harnessing the potential of your gadget.

There are several scenarios where a user needs to interfere with a port: transferring files from a flash drive without using cloud services, debugging applications by a developer, or distributing the Internet via cable. Each of these cases activation occurs differently, often not because of a hardware malfunction, but because of software constraints or non-obvious system settings that need to be activated manually.

In this article, we will discuss all aspects of working with universal serial bus on devices from the Chinese manufacturer. We will look at both standard methods of connecting drives through OTG technology, and hidden functions for advanced users. You will learn where to look for switches of modes of operation and what to do if the device does not see the connected periphery.

Activation of USB OTG function on Xiaomi smartphones

On-The-Go technology allows a mobile device to act as a host for connecting the external peripherals. Unlike some budget models of other brands, where this feature must be searched for in the settings, on most modern Xiaomi smartphones it is turned on by default and works automatically. However, if your gadget does not respond to the connection of the flash drive, it is worth checking if there are specific settings in the system.

To start with, make sure your device is physically host-friendly. Virtually all mid- and flagship models released after 2016 have this capability. You’ll need a special adapter or USB-OTG cable to connect. If no message appears in the notification curtain after connecting the external drive, manual activation via an engineering menu or third-party utilities may be required, although there is often no separate switch system in place.

Sometimes the system blocks the connection due to energy savings or driver errors. Try rebooting the device with the cable already connected. It is also worth checking the format of the storage file system: Android devices natively support FAT32 and exFAT, while NTFS may require additional plugins or root access rights to read.

  • πŸ”Œ Use a quality adapter, as cheap cables often don’t have the necessary contacts to transmit data.
  • πŸ“ Format flash drives into FAT32 Maximum compatibility without additional software.
  • ⚑ Make sure that the connected device does not consume more power than the smartphone port can give.
  • πŸ“± Check the support OTG in the technical characteristics of your model on the official website.
πŸ“Š Have you ever faced the problem of invisibility of the flash drive on Xiaomi?
Yeah, all the time.
Sometimes.
Never had a problem.
I don't use flash drives.

It is important to understand that there is no visible switch "USB OTG" The settings menu doesn't mean that the function is off, it's the system that determines the type of device that's connected, but if you're using specific hardware, like an external audio interface, or MIDI-keyboard, make sure that the application to work with them has permission to access USB-device.

Enabling USB debugging for advanced users

Debugging mode by USB (USB Debugging is a tool designed primarily for application developers, which allows a computer to gain full access to the Android system to install applications, logs, and execute commands through the application. ADB (Android Debug Bridge.For a normal user, enabling this mode may be required when flashing the device, unlocking the bootloader, or restoring the system after a crash.

To activate this feature, you need to access the hidden Developer Menu, which is hidden from the user's eyes by default, to prevent the critical settings from being accidentally changed. The activation process takes a few seconds, but requires care. You need to find the build number and quickly click on it several times.

Once you turn on the developer mode, a new item will appear in the settings menu, and when you enter it, you will find the USB Debugging switch. When you first turn on, the system will issue a warning about potential security risks. This is a standard security measure that warns that connecting to an unknown computer can give an attacker access to your data. Always confirm the connection only on trusted devices.

It is worth noting that on the shell MIUI And HyperOS has additional protection. Once you've enabled debugging in the developer menu, you also need to activate the item "USB-Debugging (Security settings).” This may require authorization through SIM-Mi Account card and account: This is a unique feature of Xiaomi’s ecosystem, aimed at combating malware and device theft.

⚠️ Warning: Do not turn on debugging by USB, In this mode, third-party programs can gain full access to your phone's file system, which creates a risk of personal data leakage when connecting to public charging stations.

Set-up of the regime USB-modem

Function USB-The modem allows you to use your smartphone’s internet connection to connect to your computer or laptop, which is especially true in situations where Wi-Fi is not available and the mobile signal is stable. Unlike a Bluetooth modem, a cable connection provides higher speeds and lower latency, while also charging the device at the same time.

To activate the mode, you need to go to the settings, select the "Access Point and modem" item and activate the switch "USB-Note that this item may be inactive (grey) if the phone is not connected by cable to the computer or if the PC does not have the necessary drivers installed. Android automatically detects the presence of a connection and allows the activation of the function.

The computer perceives the connected phone as a normal wired network connection (Ethernet). In most cases, drivers are installed automatically by the Windows operating system or macOS. However, on some corporate computers with strict security policies, the installation of new network devices can be blocked by the administrator.

Use of the USB-The modem consumes battery power, but much slower than the distribution via a Wi-Fi hotspot, and the cable connection is more difficult to "jam" or intercept by unauthorized persons, which adds a layer of security when dealing with sensitive information in public places.

Why the computer can't see USB-modem?
If your computer doesn’t recognize your phone as a network card, try changing it. USB-Sometimes the problem is a lack of power port, especially on older PCs. You may also need to manually install drivers through Device Manager, selecting the Android Composite model. ADB Interface or RNDIS.

Solving problems with connection and transfer of files

The most common problem when connecting Xiaomi to a computer is the lack of response to the cable. The user connects the device, hears the connection sound, but nothing appears in My Computer. By default, Android smartphones only connect in Charge Only mode. This is done for security reasons, so that when connecting to someone else's PC, files are not available without the owner's permission.

To fix this, unlock the smartphone screen after you connect the cable. Pull the notification curtain down from the top. You should see the notification "Click on USB Charge" or "Click on other USB actions." You click on it, you open the mode selection menu. You can select File Transfer (MTP) or Photo Transfer (PTP) here, only after that the file system will be available to an external device.

If the notification doesn't appear even after unlocking the screen, the problem may be the cable. Cheap cables often have only two veins to power and lack data lines. Replace the cable with a knowingly serviceable, preferably original, from the kit. It's also worth checking the smartphone connector: it could get dust or pile, which prevents tight contact contacts.

  • πŸ” Clean the charging connector gently with a wooden toothpick or plastic spatula.
  • πŸ”„ Rebooting both devices (PC and phone) often resolves driver software conflicts.
  • πŸ’» Install the official Mi driver PC Suite or Google USB Driver for Windows.
  • πŸ›‘οΈ Disable the antivirus on your PC while checking the connection, sometimes they block new devices.

In some cases, resetting USB helps. To do this, the "Developers" menu has "Select USB configuration." Try changing it to MTP, then restarting the phone. If that doesn't work, maybe the power controller or the port itself at the hardware level is damaged, which will require you to go to the service center.

⚠️ Warning: If the phone starts to heat up in the area of the connector or makes strange noises, immediately turn off the cable.This may indicate a short circuit inside the port or a battery malfunction, which can lead to a fire.

Use USB for audio and specialized devices

Modern Xiaomi smartphones often lack the standard 3.5mm headphone jack, which translates users to using digital audio via USB-C. Enabling support for external DACs (digital-to-analog converters) usually happens automatically. However, if you plug in a high-quality external DAC or sound card and no sound, it's worth checking the settings.

You can find a section on the Developer Menu that is related to audio, you can have the option to turn off the absolute volume level or you can choose the default audio format. USB-It's a port that might conflict with system settings, and it helps to turn off other systems. USB-Devices and Media Service Restart.

Besides audio, through USB Ethernet adapters can be connected to wired Internet, MIDI-Keyboards for musicians and even webcams. Support for these devices depends on the Android kernel and the specific processor model. Xiaomi flagship models usually have full support for the standard. USB Audio Class 2.0 and other protocols, while budget models can limit the current consumption, which will not allow you to earn energy-intensive device.
