You connected Xiaomi to your computer through USB-cable, but the system doesn't respond - the phone doesn't charge, files don't show up and "My Computer" is empty, POCO Mi: The cause can be both trivial settings and deep system failures, and 80 percent of the time, it's fixed in 5 minutes, but sometimes it takes a holistic approach.

We've analyzed hundreds of cases on 4PDA forums, Mi Community and service centers to bring all the working methods into one instruction. There's no universal magic solution here -- each section is about a specific cause, from simple to complex. Start from the first point and move consistently until the connection is restored. Pay particular attention to the hidden MIUI settings that even experienced users often ignore.

1. Checking physical connections: cable, port and charging

Start with basic hardware diagnostics. According to Xiaomi Service Center, 35 percent of the calls are USB-The problem is solved by replacing the cable or cleaning the port:

• 🔌 Try another one. USB-Use the original cable or certified cable. USB Type-C with data support (not all charging cables support data transfer) MTP). Cheap uncertified wires often have only 2 pins to power instead of 4.

If the phone is not only not defined as a drive, but also not charging via USB (or charging very slowly), it may be in Emergency Download Mode (EDL) mode.

• 🔄 Failed firmware update.
• 📉 Critical battery discharge (below 3%).
• 🛠️ Hardware failure of the power controller.

Signs of EDL mode:

• The phone doesn’t turn on, but vibrates when connected to a PC.
• In the Device Manager appears Qualcomm HS-USB QDLoader 9008.
• The screen remains black, but the backlight may be slightly glowing.

To exit the EDL:

1. Turn off the cable and hold the power button for 30 to 60 seconds (even if there is no reaction).
2. If the phone has a removable battery (such as a Redmi 4X or Redmi 5A), remove it for 2 minutes.
3. Connect to another power source (charging from the mains) and wait for the charging indicator to appear.

If the phone still doesn’t leave EDL, you’ll need firmware through the Mi Flash Tool with Clean All mode selection.

• 🖥️ Group Policies (for Windows Pro): Press Win + R, enter gpedit.msc → Computer configuration → Administrative templates → System system → Access to removable storage devices → turn off the restrictions.

On macOS, the problem may be in Android File Transfer. Uninstall the program through Finder, then download the latest version from Google. For Linux, install the mtp-tools package via the terminal:

sudo apt install mtp-tools libmtp-common

7. Hardware malfunctions: when you need help from the service

If none of these methods worked, the problem could be hardware, and here are some signs you should contact a service center:

• 🔌 Port port USB: The phone is not charged by any cable, the port is wobbly or has visible damage.
• 📱 Power Controller: The phone only charges in a certain position of the cable or when you press the plug.
• 🔋 Battery: Battery bloating can put pressure on motherboard, breaking USB-Connection (check if there is a gap between the screen and the body).
• 🔧 microcircuit USB: after falling or getting moisture (on Xiaomi models) 11T and POCO F4 This chip often fails).

Cost of repair:

Before visiting the service, back up your data via Mi Cloud or ADB backup (if the phone is responsive to the connection at all). On models with Snapdragon (such as the POCO X3 Pro), sometimes firmware via Fastboot helps, but this is risky without experience.
