Modern Xiaomi and Redmi smartphones have become an integral part of the digital workplace for millions of users. Often there is a need to quickly transfer photos, documents or music to the big screen for editing or backup. Direct cable connection is the fastest and most reliable way to transfer data, regardless of the speed of the Wi-Fi router.
However, just by inserting a cord into the connector, you may find yourself in a situation where the computer makes a connection sound, but the files remain inaccessible. This is due to the features of the MIUI shell, which by default blocks access to the file system for security purposes. To change this behavior and open full access to the internal storage, you need to follow a few simple but important steps.
In this article, we will take a closer look at the entire setup process, from choosing a quality cable to activating hidden developer features, how to avoid common bugs and why your PC may not see a device even after all the manipulations.
Selection of suitable cable and preparation of ports
The first thing that a user encounters when they fail to connect is the physical connection layer. Not all cables are the same. Many complete cords, especially thin and light ones, are designed solely for charging and have no internal data lines. If you use a third-party accessory, make sure it supports a data standard, not just current.
Pay attention to the state of affairs. USB-In Xiaomi smartphones, the Type-C or Micro-USB connector can eventually get clogged with pocket dust and pile, resulting in loose contact attachment. Carefully clean the port with a wooden toothpick or plastic spatula, avoiding the use of metal objects that can cause short circuits.
It also matters which port you connect your computer to. For stable operation and fast transfer of large amounts of data, it is better to use ports soldered directly on the motherboard (usually at the back of the system unit), the front ports of the case may give insufficient voltage or have poor contact.
- 🔌 Use the original cable out of the box or certified analogue with data labeling.
- 🧹 Check the phone charging port for dust and contact oxidation.
- 💻 Connect the device directly to the motherboard, bypassing USB-hubs.
💡
If the cable warms up during data transfer or the connection is constantly lost, try replacing the cord with a shorter and thicker one – this often solves the problem of unstable signal.
Configure the USB mode in MIUI
Once you physically connect your smartphone to your PC, the Android operating system defaults to Charge Only, a standard behavior for protecting user data from unauthorized access when you connect to other computers, and you need to manually switch the interface mode to see the files.
Immediately after you connect the cable, unblock your phone screen. Swipe from top to bottom to open the notification bar. You will see the system notification "Charge via USB" or "Setting up USB." Click on this notification to open the mode selection menu.
In the list that opens, select File Transfer (sometimes called MTP), and then the computer should display the characteristic driver installation sounds, and in My Computer, a new device with the name of your smartphone will appear.
⚠️ Note: If the File Transfer option is missing or inactive, you may have the feature enabled «USB-Disable it in the network settings before you try to change mode.
Sometimes the system suggests you choose the type of connection for a particular computer, and if you trust that PC, you can always tick "always allow" so you don't confirm the action every time, but for public computers, you'd better leave a manual choice.
Installation of drivers and work with the Device Manager
On Windows 10 and Windows 11, drivers for Xiaomi devices are usually installed automatically through the Update Center, but older versions of Windows or when using specific models (such as the Black Shark series or older Redmi) may require manual installation.
If the device appears as "Unknown Device" or with a yellow exclamation point in My Computer, check the Device Manager. Right-click on the Start button and select Device Manager. Find the Portable Device or Other Device section.
If the driver is not up, download the official Mi PC Suite utility or universal ADB drivers. You can also try to update the driver manually, indicating the path to the standard MTP USB Device drivers that are already in the Windows system.
| Type of device | Required driver | Where to find out. |
|---|---|---|
| Smartphone (MTP Mode) | MTP USB Device | Automatically in Windows Update |
| Debugging mode (ADB) | Google USB Driver | Android SDK Platform Tools |
| Modem mode (RNDIS) | Remote NDIS Compatible Device | Device Manager -> Update |
| Bootloader (Fastboot) | Xiaomi USB Driver | Mi Unlock Tool / Official website |
What to do if the driver is placed with an error?
Use of debugging mode via USB
Advanced users in firmware or deep diagnostics may need to enable debugging mode, which allows the computer to send commands to the phone, install applications, and read system logs, and requires access to the Developer Menu.
To activate the menu, go to Settings → About the phone. Find the line "Version." MIUI» And press it fast. 7-10 Once in a row, until the message "You became a developer" appears, and then a new section "Additional" or "Extended settings" will appear in the main settings menu, where the desired item is located.
Inside the “For Developers” menu, find the Debugging Switch USB And you activate it. When you first connect to a new computer, you'll see a request for debugging permission on your phone. RSA-You must click "Allow" and if you wish, "Always allow from this computer».
☑️ Checklist before debugging is included
Using debugging gives you full control of the device, but increases security risks.Do not leave this mode on permanently if you connect your phone to charging stations in public places or unfamiliar computers.
Solving Connection and Visibility Problems
Even with the right settings, there may be crashes, the computer may not respond to the connection, or the phone will only charge, often the problem lies in a software conflict or a Windows service failure.
Try rebooting both devices. This is a banal but effective tip that resets temporary errors in the work. USB-Also check if the phone is worth the Invisibility mode for the network, although it affects network functions rather than network functions. MTP.
If nothing helps, change USB-Sometimes the problem is solved by updating the drivers of the chipset of the motherboard of the computer. In rare cases, antivirus software can block the connection of external drives.
⚠️ Note: If the phone discharges quickly when connected to a PC, it may be that the cable is too thin and has high resistance, which causes the phone to consume more power to overcome resistance than it receives to charge.
💡
Changing the cable to a serviceable and high-quality one solves 80% of problems with connecting Xiaomi to a computer.
Alternative methods of data transmission
If wired connectivity is impossible or uncomfortable for some reason, Xiaomi's ecosystem offers wireless alternatives.The Mi Share app (formerly Mi Drop) allows you to transfer files over Wi-Fi Direct at a high speed comparable to Bluetooth, but much faster.
You can also use cloud services such as Mi Cloud, Google Photos or third-party solutions like Send Anywhere. FTP-server through the built-in Mi Explorer. To do this, in the conductor, you need to click on the menu and select "Network Access».
Wireless methods are convenient for transferring individual files, but for creating full backups or working with gigabytes of data. USB-cable remains the leader in speed and stability of connection.
