Tech FAQ

There are a couple steps which may be under taken to determine why an ANT USB stick is not working with your phone:

1. Your Android device must be running Android Version 3.1 or higher
2. You must be using an ANT USB2 or USBm stick along with your host cable
3. Install the ANT Radio Service
4. Install the ANT USB Service, you may not be able to if your device does not support the USB Host API
5. Use the USB Host Diagnostics App to determine if you have Android USB Host API support
   1. You have support if the app reports under Android API:
      1. Claims support: Yes
      2. Classes found: Yes
      3. Device detected: Yes
   2. If the device is not detected by the Kernel, you may not have USB Host Hardware support, please check with your manufacturer
   3. If the device is not detected by the API but is detected by the Kernel, your device may not support 3rd party apps, please check with your manufacturer
   4. If the classes are not found, that particular firmware does not support the USB Host API and needs to be updated by the manufacturer (or by an intrepid custom ROM programmer)
   5. If the classes are found, but the device is not claiming support, you may be able to enable support yourself
      1. Add /system/etc/permissions/android.hardware.usb.host.xml with the following contents:
         <permissions>
         <feature name="android.hardware.usb.host"/>
         </permissions>
      2. If you have a tablet, edit /system/etc/permissions/tablet_core_hardware.xml, adding the following content with the other permissions:
         <feature name="android.hardware.usb.host"/>
