hi
Thanks for the reply

SO I have hci_usb compiled in my kernel...
These are things I did now...
[root@localhost Pramod]# mv /etc/modules.conf /etc/modules.conf_old
copied these lines to /etc/modprobe.conf
alias net-pf-31 bluez ------> changed to -----> alias net-pf-31 bluetooth
alias bt-proto-0 l2cap
alias bt-proto-2 sco
alias bt-proto-3 rfcomm
Added "options hci_usb force_scofix=1" to /etc/modprobe.conf file...
Now I rebooted ..
When I restarted my hcid(with sdpd, audi-service autostart) I found some things that I never seen
before in /var/log/messages these are
/***This log appeared for first time*****/
Feb 13 09:48:40 localhost audio[2473]: Loading device 00:0F:DE:B1:02:42 (headset )
Feb 13 09:48:40 localhost audio[2473]: Setting 00:0F:DE:B1:02:42 as default device

Then I did
[Pramod@localhost ~]$ arecord -D bluetooth -f S16_LE test.raw

both ACL and SCO were established
I was able to record sound from headset...
But when I tried
[Pramod@localhost ~]$ aplay -D bluetooth -f S16_LE test.raw

No sound was listened on headset

I had made all the changes suggested by you. Are they done properly?
This is my hciconfig -a output

I'm not sure modprobe looks in that file. By default, it looks in
/etc/modprobe.conf. Run 'strings /sbin/modprobe | grep conf' and you can see
where it's looking.

Hm.. I wonder what is running your adapter then? Maybe it's compiled in?
If there is CONFIG_BT_HCIUSB=y in your kernel config, then it is.

-> This is some info i would like to share
-> [Pramod@localhost ~]$ cat /etc/modules.conf

-> alias bt-proto-3 rfcomm

That's an old file, and you can probably kill it. All that info should be in
the modprobe.conf now. Your alias for net-pf-31 should point to 'bluetooth',
as that is the module for bluetooth protocol on modern kernels. There is no
more 'bluez' module as far as I can tell.

I have 'lp rswitch,hold,sniff,part' in my hcid.conf, so there is those names
above in "Link policy". I'm not sure if it matters here or not but I thought
I'd mention it.
