USB bluetooth mini adapter pairs but can't send or receive files

Hi everyone,


I'm trying to make my CSR bluetooth adapter work with snow leopard 10.6.8. It is a Cambridge Silicon Radio and OSX recognizes it and I can pair any phone to my hack, but when I try to send or receive a file I get a "there was a problem connecting to the device" after a long wait.


This is what I have in System Profiler under USB

Can anybody shed some light? I already checked CSRUSBBluetoothHCIController.kext inside IOBluetoothFamily.kext and my device and Vendor ids are there, so I don't know what's going on.

I have same deviceID on mine and works OTB on all versions of OSX. Your firmware version looks like it might be out dated. Here is info from mine if it helps you to compare, the apple bluetooth version and a few other little things are different due to OSX revision, but if you can update the firmware on it in windows or something, that's where I'd start.

Also your Vendor ID in USB section not matching Vendor ID in Bluetooth section

Thanks for your answer. Unfortuntely it does appear that my firmware version is the problem. I'm looking into upgrading the firmware on it, but since it is a very cheap module I don't have much hope. I'll keep trying.

Yes, I noticed that but that is the way my computer reports it. That's how I saw that there was something wrong.
