Windows “ADB over USB” Setup


Our developers here use Mac and Linux mostly, so we have been relying on Qualcomm documentation. Please see this reference:


The qcmdm.inf and qcser.inf files mentioned we have not been able to locate, but attached to this article are two example files that are reported to work (remove the .txt extensions), though a Samsung phone was used to get the drivers installed initially, and then after that, the PC would recognize the glasses.

You need to install the Android SDK, including the google usb driver, and the JDK if you don't have those already.  Android Studio by itself is not enough.  You need the SDK tools.  When you click to download the SDK, it takes you to this page:


Scroll down the page past the Download Android Studio 2.0 green button, and either pick the Android-studio-bundle,


or make sure you also install the command line tools.  This will download the Android SDK manager, which will allow you to get the tools, among other things, including the Google USB Driver

Also added the following env variable (your version may vary...) :

JAVA_HOME    C:\Program Files\Java\jdk1.8.0_77

Append to Path  : C:\Program Files\Java\jdk1.8.0_77\bin;C:\Program Files (x86)\Android\android-sdk\tools;C:\Program Files (x86)\Android\android-sdk\platform-tools


In advance of getting adb working,  you should be able to get the glasses to show up as a mobile device, and then enable MTP. Then, you can drag and drop apk files onto the device folder, and then use the File Browser on the glasses to go find it, click it, and install it. You will need to go to System Settings->Security and check the "Unknown Sources" option, though, to run certain Apps that are not signed or signed by an unknown certificate.

You should be able to enable the glasses in MTP mode by doing this:

  1. Turn on glasses, and connect mag cable, and plug into PC
  2. In glasses, look at status bar; it will show a notification saying debugging is enabled, and it is in Android Installer mode.
  3. Press the menu button, and then select Notifications from the popup menu.
  4. Scroll down and click on the entry that lists Installer mode; this brings up a prompt to allow you to select MTP or PTP modes.
  5. Select MTP (Media Transfer Protocol).
  6. Unplug and plug in the USB to the PC; you should see the glasses as a device or directory. This should work without any special tools being installed, other than the USB driver.


To get adb working we used this site and pulled down the Android usb driver and adb driver installers.

We can't exactly "vouch" for this site, but once both are installed, adb works.  We needed to connect a Samsung phone first and then install.
