Dear All
      We're using an ANT+ usb chip on our product and install the apks from google market. Just like "ANT radio service", "ANT usb service", "ANT+ Demo" "ANT+ Plugins".
 
      After we found the usb chip and android notify to allow ANT service to access usb device,  we tried to use the ANT+ Demo to test.
      But we got below message in android logcat. Can anyone tell us what's wrong with this?
"V/AntChannel( 2943): Attempt at CLOSE_CHANNEL failed with: ANT Adapter responded with failure code: 21"
