I used widcomm drivers and they worked but I had to use an old sony ericsson phone, get it working and then use Razr then it will work. The sony ericsson worked all the time but the Razr works sometimes only.
your other option if you are not interested in the audio gateway...(listening to calls from pc speaker) then you can just use the windows XP sp2 bluetooth drivers (after sp2 there is support).. they are even better than widcomm as far as connection.
you can read all about widcomm in
it is the best source.
I got the same issue, also have to start "Audio Gateway" trough the bluetooth icon in taskbar, would be great if there's a way to automate it.
I have tried it and it works on my W2K PC just fine. It did not work on my XP Pro PC, however I am using a version of XP called 2fast XP which has alot of services turned off, this may be the reason it will not work from my XP PC.
