The Broadcom BCM92035DGROM is an older Bluetooth 2.0 module found in some laptops, desktops, and embedded systems. While it worked well on Windows XP and 7, Windows 10 often fails to detect it automatically or disables it after updates.
If your device shows up as an unknown USB device or gives a code 28 / code 43 error, don’t panic. In this post, I’ll help you find the right BCM92035DGROM driver for Windows 10 — and get Bluetooth working again.
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.
On 64-bit Windows 10, Microsoft blocks unsigned or modified drivers. The BCM92035 driver from 2012-2014 often lacks a valid SHA-256 signature.
Temporary disable:
Shift while clicking Restart.7 ("Disable driver signature enforcement").Permanent disable (not recommended):
bcdedit /set testsigning onAfter installing, re-enable: bcdedit /set testsigning off.
| Feature | Status | |---------|--------| | Bluetooth LE (Low Energy) | ❌ Not supported | | Windows 10 Settings toggle | ❌ Often disappears | | Sleep/Wake reliability | ❌ Requires re-plug or driver restart | | Multiple device pairing | ⚠️ Unstable beyond 2 devices |
Warning: Do NOT use random "driver updater" software. Many are malware. Only download from trusted sources.
Q: Is BCM92035DGROM the same as BCM92035DGROMBL? A: Yes, the "BL" suffix often indicates Bluetooth only (no WLAN combo). The driver is identical.
Q: Will this driver work on Windows 11? A: Unlikely. Windows 11 strictly enforces driver signing and has removed legacy Bluetooth HCI transport. You would need test mode, and even then, stability is poor.
Q: Why does Windows Update not find this driver? A: Microsoft removed Broadcom 2.0 EDR drivers from the update catalog in 2019 due to security vulnerabilities (CVE-2018-5383, Bluesnarfing).
Q: My Device Manager shows "Generic Bluetooth Radio" – is that the same? A: No. That is Microsoft's generic driver lacking full functionality. You must force the Broadcom-specific INF file.
Q: Can I extract the driver from my old Windows 7 installation?
A: Yes. Navigate to C:\Windows\System32\DriverStore\FileRepository\bth.inf on your old drive – but you’ll still need to disable signature enforcement.
