BT support didn't exist until a few years ago in bootcamp and when it did appear it was only for the Apple BT keyboard and mouse.
Sorry but I can't tell if you have the Apple hardware.
My issue here is this. When I try to add my bluetooth mouse or keyboard in Windows XP they will not stay in list of devices, or work ever.
This is a Logitech Keyboard and mouse. Both have worked on my computer before (right up until yesterday). When I add either devices Windows indicates the pairing was successful. The devices will show immediately after but will not work. If I click OK (with the trackpad built into my laptop) and reopen the devices list the mouse/keyboard will be gone.
This computer I'm using is a Macbook Pro running Windows through Bootcamp. My mouse and keyboard both work when I boot into Mac OS X. I have posted this same question on the Apple Discussions boards but I have not received an answer in some time. So I thought I would try here as well.
Another note: Under the services tab of the mouse (while it appears before I press OK) there is an option that says along the lines of "Use driver for mouse or keyboard HID" and that box is not checked. If I try to check this box I get a pop up window saying "Access Denied".
