Found solution for me:
Tried to restart udev:
service udev restart
(But after restarting, hal - was stopped, and new USB devices are not working in X)

I was looking at:
udevadm monitor
KERNEL[1262607846.033487] change /devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0 (scsi)

lspci

With blank disc works for me too.
At processes found:
root 9997 0.0 0.0 3416 1232 ? S 09:58 0:01 hald-addon-storage: polling /dev/sr0 (every 2 sec)

That's why I was trying to disable polling for my cdrom in hal
sudo hal-disable-polling --device /dev/sr0
Polling for drive /dev/sr0 have been disabled. The fdi file written was
  /etc/hal/fdi/information/media-check-disable-storage_model_DVD_RW_AD_7560S.fdi

After that, at process list:
root 31850 0.0 0.0 3416 1136 ? S 14:27 0:00 hald-addon-storage: no polling on /dev/sr0 because it is explicitly disabled

And now, all works fine.

p.s. Sorry for my english :)
