I have a brand new Garmin Forerunner 405.  I have installed the ANT Agent application many, many times and I am unable to get the ANT Agent to become active when I insert the USB stick.  There is always a red bar through the ANT agent logo.
I have spent several hours on the phone with Garmin S/W support.  I have exchanged the complete watch based on their reccomendation.  I have uninstalled and reinstalled many, many, many times.  I reinstalled Windows and just finished with all the updates....
This is Garmin Wireless USB1 stick on the USB port of a HP CMT D530 (WinXP Pro SP3) that I have not been able to make work.  I have installed the same USB stick on a Gateway laptop with the latest Windows and it worked fairly easily....
Ideas???
