About the size of a grape, the IOGEAR Bluetooth 2.0 USB Micro Adapter connects your computer to Bluetooth devices like cell phones, PDAs, mice and keyboards. Because it's so small, it can fit in your computer without blocking any adjacent USB ports. Its Bluetooth 2.0 + EDR technology provides for transfer rates up to 3 times faster than Bluetooth 1.1 and 1.2 adapters. Supports the following services: generic access (GAP), serial port (SPP), FAX, network access (LAP), dial-up networking (DUN), object push (OPP) headset (HSP), remote control (AVRCP), file transfer (FTP), audio gateway (A2DP), human input devices (HID) and synchronization. Includes software on CD-ROM. Requires Microsoft Windows 2000+ or Mac OS v10.3.9+.
