Hi Ljubomir,
Thanks for your suggestions, I tried kernel-ml & kernel-lt. Seems lots of error for kernel when I was starting the OS. kernel-lt is more stable. Both works fine for my bluetooth dongle. I will use the kernel-lt before CentOS release new kernel version. As my CentOS is for desktop use purpose, not so concern about the stability. Thank you so much!
Best Regards, Su Heng

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.
