hi
Thanks for the reply
I run following
[Pramod@localhost ~]$ strings /sbin/modprobe | grep conf
/etc/modules.conf
showconfig
/etc/modprobe.conf
Usage: %s [-v] [-V] [-C config-file] [-n] [-i] [-q] [-b] [-o <modname>] <modname> [parameters...]

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
Playing raw data 'test.raw' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono

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

modprobe 
looks 
in 
that 
file. 
By 
default, 
it 
looks 
in 
/etc/modprobe.conf. 
Run 
'strings

grep

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

#Bluez

#alias 
net-pf-31  
  
  
bluez

bluez

bt-proto-0 
l2cap
-> 
alias 
bt-proto-2 
sco
-> 
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.

there

I

I'd 
mention 
it.
