If you have an app running that uses the old interface (eg. ANT+ Demo or ANT+ Bike Display Demo) it will take over every ANT channel, leaving none available for apps on the new version of the interface.
With the current ANT Radio Service, you must ensure no other apps are running which use the old interface before trying to acquire a channel.
You can continue development by running the Aquire Channels Sample first and waiting for the USB stick to initialise (when the "Open New Channel" button becomes available). Then switch to your application while it is still running.
An update to ANT USB Service version: 1.3.0 on Google Play contains a fix to this problem.
