# Can I install applications on my M-Series device using USB?

Normally, applications are installed from our App Store as described [here](https://vuzix.document360.io/preview/v1/en/84b3bd72-9d77-4f92-8b55-a3c5021b5005/1). However, if you have downloaded an .apk file to your computer, you can install it via a USB connection. There are two mechanisms for this.

Without Additional Software

1. For the M300XL: Disconnect the battery from the M300XL to expose the USB Micro-B port. For the M300: Attach either a USB Micro-B adapter or the a battery to the custom connector to expose the USB Micro-B port.
2. Insert a USB-A to USB Micro-B cable between the device and a USB-3.1 high-power port on the computer. Standard USB ports on the computer do not supply sufficient power and cannot be used.
3. On the M-Series device, open Settings > Storage & USB.
4. Long-press the front button to show the menu.
5. Select USB Mode.
6. Change the mode to File transfers. The M300 should appear as a device on your computer.
7. Use your Windows File Explorer or macOS Finder to copy the .apk file to the virtual SD Card of the device.
8. On the M-Series device, open Settings > Storage & USB > explore.
9. Locate the file you copied.
10. Highlight the .apk file and click it to install.

Using Android Debug Bridge Software

If not already installed, obtain ADB software from [developer.android.com](http://developer.android.com). Follow the setup procedure so that adb is in your path. Simply issue the command ‘adb install <path to file>.apk’ in a command window.
