I have an IBM T41 with the ibm wireless a,b,g card and bluetooth wireless included. I also have a logitech cordless presenter which uses a usb blue tooth device to connect to the mouse/presenter. I have tried turning off my WiFi, and removing the USB blue tooth item from logitech and turning on the notebook's blue tooth radio. The devices never see each other. I have the most recent driver from logitech (which I never needed on my other xp pro notebook) just in case it is required for this. While using the Bluetooth usb component is not a big deal I would really like to know what the IBM bluetooth radio does and if it can work with this mouse. I went to logitechs web site but I could not find any place to leave a support email. Any suggestions would be appreciated.
