Connecting Xiaomi Redmi 7 to your computer via USB: all ways and solutions to problems

Xiaomi Redmi 7 is a popular smartphone that is still actively used thanks to balanced features and support. MIUI. However, many users face difficulties when first connecting a device to a PC through a computer. USB-Problems can range from a lack of computer response to file transfer errors. In this article, we will analyze all possible connection scenarios, configure the correct modes, install drivers and solve typical problems.

It’s important to understand that the connection process depends not only on the smartphone itself, but also on the computer’s operating system. Windows often requires additional drivers to be installed, whereas macOS or Linux may have nuances with mounting the device. We’ll look at all options, including the rare cases where the smartphone is identified as an unknown device or not displayed in the conductor.

If you haven’t worked with Xiaomi devices before, note that the manufacturer uses its own data protocols that can conflict with standard Android drivers. This is especially true for models with a locked bootloader or custom firmware. But don’t worry — we will provide solutions for each case.

Preparing the smartphone for connection

Before you connect Redmi 7 to your computer, you need to do a few preliminary steps on the device itself, which will avoid most recognition problems.

The first thing to do is unlock the screen, and many people forget that when you connect over USB, your smartphone requires you to verify your trust in your computer, if the screen is locked, the connection may not be established, and also make sure that the cable is working, because often problems arise from damaged wires or connectors.

Then check the developer settings. If they are not activated, go to Settings → About Phone and 7 times click on MIUI Version. After that, the main settings menu will be a new section For developers. Here you need to enable USB debugging - this is a mandatory step for many operations, including firmware and work with ADB.

• 🔓 Unlock the smartphone screen before connecting
• 🔌 Use the original. USB-cable (or certified cable)
• 📱 Activate the developer mode (7 taps according to the version) MIUI)
• 🔧 Turn on Debugging. USB developer-side

💡

If you don’t have the original cable, try connecting via another USB port on your computer – sometimes the ports on the front of the system unit are unstable.

Choice of regime USB-connection

When you connect Redmi 7 to your PC, the USB mode option appears in the smartphone notification area. Charging mode is usually set by default, which does not allow you to transfer files. You need to manually change it to one of the available options:

• 📁 File transfer (MTP) — standard mode for data exchange
• 🖥️ Transmission of photo (PTP) — picture-work
• 🔌 Charging only – blocks access to data
• 📡 USB-modem - for distribution of the Internet
• 🔧 Mid - rarely used, may be required for firmware

For most tasks, MTP (Media Transfer Protocol) mode is suitable. However, if the computer can't see files, try PTP - sometimes it works more stable. Note that when you change mode, you may need to reconnect the cable.

On Redmi 7 with MIUI 12 firmware and higher, USB mode can be reset to Charge Only after rebooting, a feature that has only been patched in recent software versions, and if you encounter such a problem, you'll have to reset the mode every time.

Installation of drivers on Windows

Windows doesn’t always automatically recognize the Xiaomi Redmi 7 as a media device, and drivers are often required manually, especially if you plan to use ADB or Fastboot.

The official drivers for Xiaomi can be downloaded from the manufacturer’s website or use the universal Mi PC Suite. Alternatively, drivers from Google (Android SDK), which are suitable for most devices.

1. Connect your smartphone to your PC in file transfer mode
2. Open Device Manager (Win+X → Device Manager)
3. Find a device with a yellow exclamation point (usually under "Other Devices")
4. Update the driver manually, specifying the path to the downloaded files

If the smartphone is still undetected after installing the drivers, try disabling the driver signature in Windows.

1. Press Win+X → Execute


2 Enter shutdown /r /o /f /t 0




3. After rebooting, select "Diagnostics → Additional settings → Download options → Reboot"




4. Press F7 to disable mandatory driver signature verification

Connection to macOS and Linux

Mac and Linux users often find that Redmi 7 is not automatically mounted, and macOS requires installing Android File Transfer, Google's official app, download it from the developer's website and follow the instructions.

On Linux, the situation is more complicated because of the variety of distributions. In most cases, it is enough to install mtp-tools and libmtp. For example, for Ubuntu, do:

sudo apt update


sudo apt install mtp-tools libmtp-common libmtp-runtime

If the device is not identified, check the access rights:

lsusb

Find the Xiaomi list and write down its ID. Then add a rule for udev:

sudo nano /etc/udev/rules.d/51-android.rules

Add a line (replace idVendor with your ID):

SUBSYSTEM=="usb", ATTR{idVendor}=="2717", MODE="0666", GROUP="plugdev"

Save the file and restart the system.

Transfer of files between devices

Once you've successfully connected, you can start sharing data. In Windows Explorer, your smartphone will appear as a removable drive. On macOS, open Android File Transfer, and on Linux, use any file manager (such as Nautilus or Dolphin).

Transfer speed depends on the version USB-Port and cable quality.Redmi 7 supports USB 2.0, so the top speed will be about 480 Mbps to speed up the process:

• 📂 Transfer files with archives (ZIP/RAR)
• 🔄 Use it. USB 3.0 port on the computer (blue connector)
• 🚫 Avoid transmission while charging (this reduces speed)

If files are not copied or errors appear, check:

• 🔌 Faulty cable (try another one)
• 🔧 Damaged. USB-port
• 📱 Failure in the firmware (solved by resetting settings)

⚠️ Note: If a message appears when connecting to Windows "USB-Device not identified, do not click on "Driver Search in Update Center" in any case, this often leads to incompatible drivers installed.

Additional connectivity options

In addition to standard file transfers, USB-Connection gives access to advanced functions:

• 🔧 ADB and Fastboot: for firmware, unlocking the bootloader or debugging
• 🖥️ PC management: via Scrcpy or Vysor
• 📡 USB-Tethering: Internet distribution from the phone
