Hi All,
I bought a USB Bluetooth dongle.
However, it's not working for me. Please help, how to debug and get more information as I can not see any error or warning message from system log message.
I checked http://thread.gmane.org/gmane.linux.bluez.kernel/22183/focus=22211, however, also find another page https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/... said already support BCM20702A0.
Please help, thank you.

You can try with newer kernels from ElRepo (http://elrepo.org/tiki/tiki-index.php) that have compatible API's with EL6. look for elrepo-kernel section on main page. Currently there are kernels 3.0.83-1 and 3.9.7-1. But do note that those are third party kernels, even though ElRepo is safe third party repository.
