"I have a Targus AMB01US (Bluetooth Mini Mouse) and after reformatting my laptop I went to reinstalling the mouse. It seems the original Broadcom BTW driver, whether it was from the install CD or included in Windows, was corrupted. The mouse's install CD was no help so I downloaded this driver to replace the corrupted copy and it works! It still needed the original install
