The Xiaomi ADB USB driver is what lets a Windows PC talk to a Mi, Redmi, or POCO phone over the Android Debug Bridge. Without it, ADB commands fail, the device shows as "unknown", and tools cannot see the phone. This guide explains what the ADB driver does, how to install it, how to enable USB debugging on a Xiaomi device, and how to fix the connection problems technicians hit most.

What Is the Xiaomi ADB Driver?

ADB (Android Debug Bridge) is the command interface Android uses for debugging, sideloading, and low-level device control. The ADB USB driver is the Windows component that maps the phone's ADB interface so commands like adb devices actually detect it. On Xiaomi phones running MIUI or HyperOS, ADB is used for pulling logs, removing bloat, sideloading updates, and preparing a device for deeper service work.

When You Need the ADB Driver

  • Running adb devices, adb reboot, or sideloading a package.
  • Removing pre-installed apps or debugging a misbehaving device.
  • Preparing a Xiaomi phone before fastboot or flashing work.
  • Any PC tool that communicates over ADB rather than fastboot or EDL.

How to Install the Driver (2026)

  1. Download the driver package and extract it to a simple folder path with no spaces.
  2. If it is an installer (.exe), run it as Administrator and follow the prompts.
  3. For a manual INF install, open Device Manager, find the phone under "Other devices" with a yellow mark, right-click and choose Update driver.
  4. Select Browse my computer, point to the extracted driver folder, and let Windows install it.
  5. If Windows blocks an unsigned driver, reboot with driver signature enforcement disabled and repeat.

How to Enable USB Debugging on Xiaomi

  1. Go to Settings > About phone and tap MIUI/HyperOS version seven times to unlock Developer options.
  2. Open Settings > Additional settings > Developer options.
  3. Turn on USB debugging (and USB debugging (Security settings) if you need install permissions).
  4. Connect USB, then tap Allow on the "Allow USB debugging?" prompt on the phone.

Common Problems and Fixes

  • Device not listed in adb devices: Driver not installed or USB debugging off — reinstall the driver and re-check debugging.
  • "Unauthorized" in ADB: The authorise prompt was missed — revoke USB debugging authorisations and reconnect.
  • Unknown device / Code 10: Bad driver or cable — reinstall via Device Manager and use a USB 2.0 port.
  • Prompt never appears: Switch USB mode to File Transfer (MTP) first, then reconnect.

Supported Models

The Xiaomi ADB driver covers the whole Mi, Redmi, and POCO line-up on MIUI and HyperOS — from budget Redmi and POCO models to flagship Mi and Xiaomi-branded devices. Because ADB is standardised across Android, one correctly installed driver serves every Xiaomi device you are likely to service.

Frequently Asked Questions

Is the ADB driver the same as the fastboot driver? They are related but separate interfaces — see the Xiaomi Fastboot USB driver guide for fastboot mode.

Do I need to unlock the bootloader for ADB? No — ADB and USB debugging work on a locked bootloader.

ADB works but fastboot does not — why? They use different drivers and modes; install the fastboot driver separately.

Will enabling USB debugging wipe data? No, it only enables the debug interface.

Windows Driver Signature and Installation Notes

Most driver failures on modern Windows come down to signature enforcement and leftover installations rather than a bad download. Windows 10 and 11 block unsigned drivers by default, so if the install appears to succeed but the device still shows a yellow warning, reboot with driver signature enforcement disabled and repeat the manual installation. Old or partial driver entries also cause trouble: if a previous attempt left a broken device in Device Manager, uninstall it with the "delete the driver software" option ticked, unplug the phone, and start fresh. Finally, antivirus software sometimes quarantines driver packages and flashing tools, so pause it during installation and re-enable it afterwards. Getting these three things right — signature, clean slate, and antivirus — resolves the large majority of Xiaomi ADB driver problems before you touch anything else.

Common Real-World Cases

A Redmi that returns an empty list from adb devices almost always has the driver missing or USB debugging switched off. A Mi phone showing "unauthorised" simply missed the on-screen allow prompt, cleared by revoking authorisations and reconnecting. A POCO that connects for charging only is usually still in the wrong USB mode, fixed by switching to File Transfer. And a device that worked yesterday but not today has often had a Windows update replace the driver. Recognising which of these patterns you are looking at turns a vague "the PC does not see my phone" complaint into a quick, targeted fix, because each one has a distinct and predictable cause. In practice, the driver itself is faulty far less often than the cable, the port, the USB mode, or the device-side setting, so working through those in order saves a great deal of time in a busy workshop.

Pro Tips for a Stable Connection

  • Use a rear USB 2.0 port: USB 3.0 ports and hubs are behind a large share of dropped connections during ADB command-line work.
  • Keep one known-good cable: Label a cable that you trust and use it for every service job — cheap cables cause faults that look like driver problems.
  • Install drivers before connecting: Set up the ADB interface on MIUI and HyperOS first, then plug in the phone, so Windows binds the right driver from the start.
  • Check Device Manager, not the tool: Confirm the correct port appears in Device Manager before blaming the flashing software.
  • Keep the battery charged: A low battery can cause disconnects and failed writes that mimic driver errors.

Conclusion

The Xiaomi ADB USB driver is the foundation for any ADB-based work on Mi, Redmi, and POCO phones. Once ADB is connected, move on to the Xiaomi Fastboot driver for bootloader tasks or the Xiaomi EDL driver for deep flashing, and pair them with the Xiaomi MiFlash tool guide for firmware.
