If you are searching for the correct driver, it is best to prioritize sources in this order:
That is the default hardware string stored in the chip’s EEPROM. Windows 10 does not recognize it, so it displays the raw HWID. Installing the correct driver changes the name to “Broadcom Bluetooth Device.”
This device is commonly found embedded in older Dell, HP, Acer, and Toshiba laptops, as well as some mini-PCIe Bluetooth adapters from the late 2000s to early 2010s. The "DGROM" suffix indicates a specific firmware revision.
Microsoft changed the Bluetooth stack entirely after Windows 8. Windows 10 uses a native, universal Bluetooth driver model. The BCM92035DGROM uses an outdated HCI transport protocol that Windows 10 does not recognize natively. Bcm92035dgrom Driver Windows 10
You can try forcing an old Windows 7 Broadcom driver (e.g., from a Dell or HP support site) using "Have Disk" in Device Manager. This often works functionally but comes with risks:

If you have landed on this page, you are likely staring at an unknown device in your Windows 10 Device Manager with a yellow exclamation mark, marked simply as “BCM92035DGROM.” The name alone can be intimidating, but it is not a virus or a complex piece of malware. Instead, the refers to a specific hardware identifier (HWID) for a Broadcom Bluetooth Radio .
Windows Update sometimes replaces working drivers with generic Microsoft ones. To prevent this: The "DGROM" suffix indicates a specific firmware revision
You are trying to install a 32-bit driver on 64-bit Windows 10 or vice versa.
The BCM92035DGROM refers to a Bluetooth dongle (USB) built around the chipset. It was common in the Windows XP and Windows Vista era.
