New Broadcom Chip on BCM943602CS Card?

[derpuma]

Hi the-darkvoid, rehabman?, just want to let you know, that I bought a BCM943602CS with PCI-E Adapter at ebay. System Profiler detected the BT Part of the Card under USB as BCM2045A0 (0x05ac/0x21ff)! I had to duplicate a key in the info.plist of your BrcmPatchRAM2.kext an modified it to match my device 0x21ff: <key>0a5c_21ff</key> <dict> <key>CFBundleIdentifier</key> <string>com.no-one.BrcmPatchRAM2</string> <key>DisplayName</key> <string>Broadcom BCM20702 Bluetooth 4.0 +HS USB Device</string> <key>FirmwareKey</key> <string>BCM20702A1_001.002.014.1443.1463_v5559</string> <key>IOClass</key> <string>BrcmPatchRAM2</string> <key>IOMatchCategory</key> <string>BrcmPatchRAM2</string> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>idProduct</key> <integer>8703</integer> <key>idVendor</key> <integer>2652</integer> </dict>

Also I had to make a change in the S/L/E/IOBluetoothFamily.kext/Contents/PlugIns/BroadcomBluetoothHostControllerUSBTransport.kext/Contents/Info.plist I had to duplicate an IOClass key to match my vendor and device id: <key>IOClass</key> <string>BroadcomBluetoothHostControllerUSBTransport</string> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>idProduct</key> <integer>8703</integer> <key>idVendor</key> <integer>2652</integer> </dict>

After that, the Broadcom BT was detected and fully working under OSX Sierra! Maybe this is a new chip you have not integrated so far in your BrcmPatchRAM2.kext and you want to include it.

If you have any questions, feel free to ask!

but this driver can only made the device manager showing bluetooth driver installation ok. when trying to discover bluetooth devices, noting will be found. it seems that the firmware is not included in the driver for the combined PCIE wi-fi & bluetooth BCM943602CS. and after installed this driver on Windows 10 then reboot to macOS, also can't discover any bluetooth devices and can switch off bluetooth but can't switch it on again.
