Q3: What if I want to use your hardware products with different Bluetooth-enabled software and with my internal Bluetooth-enabled radio?

A3: Microsoft hardware products can only be guaranteed to work with the Bluetooth support in Windows XP Service Pack 2. The basic functionality of the Microsoft hardware may work if the other Bluetooth-enabled software has passed the Bluetooth certification for the following profiles that are defined by the Bluetooth SIG:

• The Human Interface Device profile
• The Hard Copy Cable Replacement profile
• The Dial-up Networking profile
• The Serial Port profile

Q4: I have a computer that has Bluetooth built in. Can I use the Microsoft Bluetooth-enabled keyboard and mouse without using the USB transceiver?

A4: You might have this question if you have a portable computer that is Bluetooth-enabled. The Wireless Optical Desktop for Bluetooth includes the USB transceiver because few desktop computers support Bluetooth. If your computer has Bluetooth built in and if your computer has the Human Interface Device profile, you may be able to connect the Bluetooth-enabled keyboard and mouse directly. If you want to use a specific internal Bluetooth-enabled radio, contact the manufacturer of your portable computer to determine whether the internal Bluetooth-enabled radio is supported by Windows XP Service Pack 2. Over time, this issue may disappear as manufacturers offer newer radio firmware.
