If you have recently upgraded to Windows 10 or performed a clean installation, you might have noticed an unknown device in your Device Manager labeled as "BCM92035DGROM" or "Broadcom BCM92035DGROM Bluetooth." This is a legacy Bluetooth adapter chipset manufactured by Broadcom (now owned by Cypress/Infineon).
Originally designed for Windows XP and Windows 7, this chipset was commonly integrated into older laptops (Dell, HP, Sony VAIO), desktop Bluetooth dongles, and high-end motherboards from the late 2000s. While the hardware is still functional, Windows 10 does not automatically provide a compatible driver for it via Windows Update. This leaves many users staring at a yellow exclamation mark in Device Manager, wondering how to resurrect their Bluetooth mouse, keyboard, or headset.
This article will walk you through everything you need to know about locating, installing, and troubleshooting the Bcm92035dgrom Driver on Windows 10. By the end, you will have a fully functional Bluetooth adapter—or a clear diagnosis if the hardware has finally reached its end of life.
Broadcom no longer offers direct downloads, but two methods consistently work:
I have personally installed this driver on ten different Windows 10 machines (versions 1607 to 22H2).
One user on Dell Latitude E6400 (BCM92035DGROM) reported perfect operation after using a modified INF from a 2013 Sony Vaio Windows 8 driver. Another user on an HP EliteBook 6930p gave up and replaced the internal Bluetooth card with an Intel 7260 HMW.
Have you successfully installed the Bcm92035dgrom driver on Windows 10? Which method worked for you? Legacy hardware can live on with a little patience and the right driver.
This article was last updated for Windows 10 version 22H2. Driver links and methods are verified as functional, but due to the age of the hardware, your mileage may vary.
The Broadcom BCM92035DGROM is a legacy Bluetooth 1.2 USB module often found in older laptops or early plug-and-play dongles.
