Thank you for answer.
I'm sure that modules loaded:
svs-zaurus:~# lsmod|grep sco
sco                    11396  0
snd_bt_sco             13868  2
snd_hwdep               7620  2 snd_bt_sco
snd_pcm                84613  8 snd_bt_sco,snd_soc_pxa2xx,snd_soc_core,snd_pxa2xx_ac97,snd_ac97_codec,snd_pxa2xx_pcm,snd_pcm_oss

bluetooth              52736  10 sco,rfcomm,l2cap,dtl1_cs
svs-zaurus:~#

Also I'm sure that devices was paired.
I check /var/lib/bluetooth/<BT_ADDR>
And also I can cat > /dev/rfcomm[0|1] which is tty of headset

Here is some part of hcidump while sco connect:
