Additional Notes
This is the driver for the Broadcom BCM4310 "USB" Controller found in many laptops (It is actually a wireless LAN device). My laptop was the HP dv2845se which comes with windows vista and has this device in it. HP does not provide a windows XP driver for this adapter on my laptop and I wanted to downgrade to XP, so the driver provided is from a dv6701us laptop with the same chipset. To get the driver to work, simply run the EXE file and the computer will detect the driver and ask you for wireless network settings.
