np44 Posted July 18, 2020 Share Posted July 18, 2020 I have an old bluetooth dongle which I found today and decided to use it, but after pluging it in it's not working. Here's details: USB Bus Bluetooth HCI: Product ID: 0x0001 Vendor ID: 0x0a12 (Cambridge Silicon Radio Ltd.) Version: 19.15 Speed: Up to 12Mb/sec Location ID: 0x5d200000 / 1 Current Available (mA): 500 Current Required (mA): 0 Extra Operating Current (mA): 0 I searched in google and tried everything, but didn't succeeded to see Bluetooth in Settings and Network. Is it possible to make it work? Link to comment Share on other sites More sharing options...

If you look into the PlugIn of IOBluetoothFamily kext, you'll notice this: <key>CSRUSBBluetoothHCIController</key> <dict> <key>CFBundleIdentifier</key> <string>com.apple.iokit.CSRBluetoothHostControllerUSBTransport</string> <key>IOClass</key> <string>CSRBluetoothHostControllerUSBTransport</string> <key>IOProviderClass</key> <string>IOUSBHostDevice</string> <key>idProduct</key> <integer>1</integer> <key>idVendor</key> <integer>2578</integer> </dict> Nothing shows in SysInfo->Hardware->Bluetooth? Are you using a full vanilla installation or a distro? I found a topic on another forum where they said version 19.15 is unsupported. Edit: I'm using full vanilla install, and nothing shows in System Info Bluetooth. Edit 2, 2021: I managed to get it show up in Catalina by using BrcmPatchRAM's BrcmBluetoothInjector.kext. I went to Contents/Info.plist and manually added it to the end, but I can't connect to my airpods. It can find devices you can click to connect, but 2-3 seconds after it's connected it disconnects. Pairing with my iPhone worked the same way - Connect > Enter PIN > Connected and after 2-3s later Disconnected.
