Xiaomi Yi action cameras have gained popularity due to their excellent price-to-quality ratio, but many users have difficulty connecting the device to the computer directly. The standard insert-and-forget method often doesn’t work without the camera itself being prepared.
The main difficulty is that by default the camera operates in storage or charging mode, but does not transmit data in the way that smartphones do. USB-connection must change the settings inside the device menu or install specialized software.
In this guide, we’ll take a look at all the nuances of connectivity, including the webcam mode that turns your action camera into a full-fledged streaming tool, and you’ll learn which cables fit, how to install drivers, and what to do if your computer doesn’t see the device.
Equipment preparation and cable selection
The first step before connecting Xiaomi Yi via USB is to make sure that the physical connection is in good working order. Not all micro-USB cables are the same: some are designed solely for charging and have no data lines.
Note the camera port. In different models (Yi 4K, Yi Action, Yi 4K+), connectors can be arranged differently, and their condition affects the stability of the connection. Dirt or oxidation of contacts often causes the PC to not respond to the connection.
- 🔌 Use the original micro-USB cable or certified analogue with Data Transfer support.
- 💻 Connect the camera directly to the motherboard port, avoiding USB-hubs without external power.
- 🔋 Make sure the battery in the camera is at least 20% charged to avoid a sudden shutdown.
If you use adapters or extension cords, signal quality may deteriorate, leading to interruption of file transfer or unstable operation in webcam mode.
Setup of camera modes
The key is to set the camera up properly. Unlike smartphones, Xiaomi Yi doesn’t always automatically offer a choice of connection mode when connecting to a PC. You need to manually activate the required protocol through the device menu.
To access the settings, turn on the camera and go to the menu. Find the connection section. Depending on the firmware version, the path may differ, but the logic remains the same: switch USB mode from Charge Only to Drive Mode or Webcam Mode.
⚠️ Warning: When you switch modes, the camera may reboot. Do not remove the cable at this point so as not to damage the file system.
Once you select USB Mass Storage, the camera will be visible to your computer as a flash drive, but if your goal is streaming, choose Webcam mode, which activates the transmission of the video stream.

Instructions for connecting to Windows and macOS
The process of connecting to different operating systems has its own peculiarities: in Windows, the system can request the installation of drivers automatically, but sometimes manual intervention is required. in macOS, the camera is usually defined as an external storage device without unnecessary questions.
First, connect the cable to the camera and computer. The camera screen should show a notification. If this does not happen, check the settings in the Settings menu -> USB. Once confirmed on the camera screen, the computer will emit an audible connection signal.
☑️ Connection check
If you’re using a Mac, you may need Android File Transfer or similar, as macOS doesn’t have full support for Android camera file system built-in in some modes.
Using Xiaomi Yi as a webcam
One of the most useful features is using the camera as a webcam for video calls or streaming. The quality of Yi 4K or Yi Action optics is far superior to most embedded laptop webcams.
There's a special mode that turns the camera into a video capture device, and when you turn it on in the camera menu, it stops being just a storage device and starts streaming video, and the computer perceives it as a standard webcam.
- 🎥 Select the mode in the camera menu "USB Camera or Webcam".
- 🖥️ Open the program for video communication (Zoom, Skype, OBS) Choose Xiaomi Yi as your source of video.
- 🎙️ Note that sound in this mode may not always be transmitted, check the audio settings in the application.
⚠️ Attention: In webcam mode, the camera can get very hot. Ensure good ventilation of the device during prolonged operation.
For professional video streaming, such as OBS Studio, you can set bitrate and resolution directly through the video source settings, which gives you flexibility that you don't have with conventional webcams.
💡
To reduce heat in webcam mode, remove the battery and connect the camera to an external power source via a special mod case or battery pack if your model allows it.
Solving problems with drivers and recognition
A common problem is that the computer can't see Xiaomi Yi. This may be due to the lack of ADB or MTP drivers on the system. In Windows 10 and 11, drivers are usually installed automatically, but older versions or crashes require manual installation.
Check Device Manager. If you see a device with a yellow exclamation point or an "Unknown Device," the driver is not installed. You'll need to download the universal MTP driver or the specific driver for the Ambarella chipsets that are used in Yi cameras.
| Problem. | Possible cause | Decision |
|---|---|---|
| The computer makes sound, but there is no disc. | Wrong USB mode | Switch to the camera menu on "Storage" |
| The camera is just charging. | Poor quality cable | Replace the cable with a data cable |
| Copying errors | Damage to the file system | Check it out. SD-misscard |
| No image in Skype | Occupied by another appendix | Close other programs that use the camera |
It’s also worth checking if antivirus is blocking the connection of a new device, and sometimes a firewall can prevent you from connecting to your data.
💡
In 90% of cases, the problem is solved by replacing the micro-USB cable with a known serviceable one that supports data transfer, not only charging.
File transfer and memory card management
Once connected successfully, you get direct access to the file system. Video files are usually stored in the DCIM folder. folder structure can be complex, so it's important to know where to look for specific materials.
When working with high-volume (4K video) files, copy speeds can be slow, a limitation of the USB 2.0 interface used in most Xiaomi Yi models. Don't interrupt the copying process so as not to damage the video files.
- 📁 folder DCIM contains all photos and videos.
- ⚙️ folder CONF Stores configuration files of camera settings.
- 🔊 folder SOUND Contains systemic sounds and greetings.
To speed up, it is recommended to periodically format the memory card through the camera menu, rather than through the computer, which helps to avoid file system errors and broken sectors.
