The Identity Crisis

The BCM2045A0 is not a standalone chip. It is a Bluetooth radio chip manufactured by Broadcom. However, on most modern laptops and desktops, this chip is rarely the primary Bluetooth adapter. Instead, it is almost always a subordinate component—typically part of a Wi-Fi/Bluetooth combo card (like those from Dell, HP, or Lenovo) or, more commonly, embedded inside a separate USB dongle (often for a wireless mouse, keyboard, or game controller).

• Search the PC/laptop manufacturer’s support site for a Broadcom or Widcomm Bluetooth driver matching your model and Windows 11 (or Windows 10 if no Win11 version exists).
• If the manufacturer site lacks Windows 11 drivers, try the latest Windows 10 Broadcom/Widcomm driver—install it in compatibility mode if needed:
