As of 2024, Broadcom has discontinued official support for the BCM2035B. The official download pages for these legacy drivers have largely been archived or removed.
Q: Can I use the BCM2035B on a Mac?
A: macOS does not include drivers for this chipset. However, some Linux distributions (e.g., Ubuntu) with the btusb kernel module can drive it.
Q: Does the BCM2035B work with Linux?
A: Yes, often out of the box. The btusb driver in kernels 2.6 and above supports the BCM2035B. Install bluez utilities for full functionality. bcm2035b usb bluetooth driver
Q: Why does my BCM2035B dongle have a yellow exclamation mark in Windows 10? A: Because Microsoft removed the legacy Broadcom driver from the Windows Update catalog. You must manually install the driver as described above.
Q: Is there a signed driver for Windows 10/11? A: No. Broadcom never released a WHQL-signed driver for Windows 10 for this chipset. You must disable signature enforcement or use a test signing mode.
Q: Can I extract the driver from an old HP/Lenovo recovery disk?
A: Absolutely. Many OEM recovery disks contain the Broadcom driver package in the C:\SWTOOLS\DRIVERS\ or C:\Drivers\Bluetooth folder. | Issue | Fix | |-------|-----| | Device
"Device Cannot Start (Code 10)" This is the most common error for legacy Bluetooth on Windows 10/11. It usually means the operating system cannot initialize the firmware.
The "CSR" Clones If you purchased a cheap USB dongle that identifies as a BCM2035B but the drivers refuse to work, you may have a "clone" chip. Many cheap dongles report false hardware IDs.
Sometimes, the driver exists in the Microsoft database, but Windows doesn't pull it automatically. You have to force it to look. "Device Cannot Start (Code 10)" This is the
Warning: This method works occasionally, but often the specific BCM2035B entry is missing in newer Windows 10/11 builds.
Even after installing the BCM2035B USB Bluetooth driver, you may encounter problems.
Some third-party dongles (e.g., from D-Link, IOGear, Belkin) have the chipset labeled on the PCB. However, most are unmarked. The Hardware ID method is more reliable.
