Based on the hardware IDs provided, this guide covers the Broadcom BCM20702A0 Bluetooth chipset. This chipset is commonly found in aftermarket mini-PCIe/WiFi cards (often sold as "BCM94352HMB" or "DW1550") used for upgrading older laptops, as well as various generic USB Bluetooth dongles.

"Best patched" usually refers to getting this device working correctly on macOS (Hackintosh), as this specific VID/PID combination often represents a "generic" or "rebranded" device that requires a specific mock ID to function with native Apple drivers.

Here is the guide for the best patched configuration.

Step 1: Confirm the Hardware Type

Before patching, ensure you aren't fixing the wrong thing. Right-click the unknown device > Properties > Details > Hardware Ids.

  • If it shows USB\VID_346D&PID_5678\MI_00 – It is likely a camera sensor.
  • If it shows USB\VID_346D&PID_5678\Class_FF – It is a generic vendor-specific device (like a JTAG or Arduino clone).

Step 2: The "Best Patched" Strategy

To achieve "native" functionality (Continuity, Handoff, AirDrop), we must tell macOS that this device is actually a legitimate Apple-branded Broadcom card.

The most stable "Mock ID" for this chipset is usually the Broadcom BCM20702 (Apple native) variant.

  • Current ID: VID: 346d PID: 5678
  • Target Mock ID: VID: 0a5c PID: 8213 (or sometimes 0a5c: 2112 depending on the specific variant).
