1. Verification of physical components: cable, port and connector

The first thing to rule out is mechanical damage, and even a microcrack in the cable or a dust that enters the port can interrupt the connection.

• 🔌 Try another cable: Xiaomi's original cables (especially from the Redmi Note 10 Pro or Poco bundle) F3) Support data transfer at speeds up to 480 Mbps. Cheap analogues often work only for charging.

USB Settings on Smartphone: Why MIUI Blocks Data Transfers

By default, MIUI (especially version 12.5-14) restricts access to files via USB for security reasons. Unless you have manually changed settings, the phone can be defined as a Charger instead of File Transfer.

1. Connect your phone to your PC via USB.
2. Flick the top notification curtain on Xiaomi.

2. Tap 7 times on the MIUI version to activate the developer mode.
3. Back to Settings → Additionally. → For developers.
4. Find the option "Configuration" USB by default and select MTP.

On some models (e.g. Poco) X3 Pro) this paragraph may be referred to "USB-configuration" or "Mode USB". If the transmission does not work after that, check if the antivirus does not block access to the PC (for example, Avast or Kaspersky often interfere with the transmission). MTP-linkage).

Windows Driver Problems: Why Your Computer Can't See Xiaomi

If the phone charges but is not defined as a drive, 90% of the time the missing or outdated drivers are to blame. Windows 10/11 automatically installs the universal MTP driver, but it often conflicts with Xiaomi firmware.

MIUI firmware (especially global versions) often contain hidden restrictions on transferring data over USB. For example, in the Redmi Note 11 with MIUI 13, access to system folders (/data, /system) is disabled by default, and in the Poco F4 GT, file transfers larger than 4 GB can be blocked.
