Hi,

My problem is as follows:

I have a usb bluetooth dongle, but I don't know the vendor of it as I lost the installation cd, therefor I don't know what driver to install, but luckily XP SP2 has inbuilt drivers.

At work, on my windows xp professional sp2 system it works fine, I just plug it in and windows recognizes it and installs following drivers:
Generic Bluetooth Radio
Microsoft Bluetooth Enumarator

An bluetooth icon also shows up in the traybar and on the controlpanel with all the options available.

BUT, at home, on a fresh installed windows xp professional sp2 system with all updates it doesn't work using exactly the same usb bluetooth dongle. Sure, the system recognize the bluetooth dongle and installs the same drivers, but the icon is missing from traybar and controlpanel, and running start > run > bthprops.cpl doesn't work (nothing happens)

At first, I thought the bluetooth device wasn't whql certified, but since it works fine at my work computer this can't be the case.

on my home computer I tried disabling serial/parallel port in bios to free up more irq, and unplugging other usb devices except mouse & keyboard. Still no luck. I also tried changing to different usb ports (all uses usb 2.0) , still no luck.

"Your hardware is ready to use", but no bluetooth icon in traybar or controlpanel.

... I'm out of ideas!
