Hi Pavan,

When hciattach calls the HCIUARTSETPROTO ioctl, you get the following
trace in the kernel:
hci_uart_set_proto -> hci_uart_register_dev -> hci_register_dev -> hci_notify.

The last function notifies user space (hcid) about the new device.
Hciattach does not use dbus and does not directly communicate with hcid.

Regards,
Ohad.
