Connecting a Xiaomi smartphone (including the Redmi, POCO, Mi series) to a computer seems like a simple task β until you encounter errors like βDevice not recognizedβ or lack of access to files. The problem is complicated by the fact that the manufacturer regularly updates the MIUI firmware, and Windows does not always correctly recognize new models. In this article, we will analyze all the current ways of connecting (USB, Wi-Fi, ADB, Mi Assistant), and solve typical errors associated with drivers, data transfer modes and MIUI security settings.
Xiaomi devices feature proprietary MTP (Media Transfer Protocol) mode, which often conflicts with Windows 10/11 drivers. In addition, the latest versions of MIUI 14+ have additional restrictions on access to files via USB due to security policies, we will show how to circumvent these restrictions legally, without root rights or the risk of blocking the Mi Account.
If you just need to copy a photo or music, the standard one is enough. USB-cable and file transfer mode enabled, but for debugging applications (ADB), backup through Mi PC Suite or remote control will require additional settings, followed by step-by-step instructions for each scenario.
1. Connecting Xiaomi to a PC via USB: the basic method
The most common way is to use a USB-TypeC cable (or MicroUSB for older models), but even here there are nuances: not all cables support data transfer (some only charge), and the default MIUI can be enabled with Charging Only mode.
To connect correctly:
- Use an original cable or a certified one (marked USB 2.0/3.0 Data Cable). Cheap cables often don't transmit data.
- Connect your smartphone to USB-port on the motherboard (not through the hub or the front panel of the system unit - there may be a lack of power there).
- On the Xiaomi screen, a notification will appear βCharge via USB.β Tap it and select File Transfer (MTP).
If the MTP item is not in the menu:
- π§ Go to Settings. β Connection and sharing β USB and manually select File Transfer Mode.
- π Reboot your smartphone and reconnect.
- π₯οΈ On PC, update drivers (more on this in the section about errors).
