Can anyone point me in the right direction or a way of upgrading my firmware in my Compaq Multiport Bluetooth in an attempt to get it to operate correctly with SP2.

I can get SP2 to recognise it as a Bluetooth radio by adding the PnP code to the CSR group in C:\WINDOWS\inf\bth.inf and it can detect my iPaq, but it cannot send a passkey, at least it thinks it is sending it, but my iPaq never gets the message. My Acer dongle works fine with the iPaw so I guess it is the Multiport and getting an updated firmware, currently 1.14. I understand that somewhere I can find a generic firmware updater. I have found one for TDK here - http://www.tdksystems.com/content.asp?id=13 - however I cannot get it to update however much I hack about the .inf file, even though it appears possible - http://forum.gsmhosting.com/vbb/showthread.php?t=111358.

Can anyone help?

Thanks in advance
