But I haven't seen any code inside hci_event_packet to notify the user socket. (Maybe I am blind..) In scotest program, there is a debug message below accept(), so that I know when it is returned from the accept() call. >From my tracing, I thought the user accept() will eventually wait inside sco_sock_accept(), which keeps itself in the wait queue. And I guess the function return of sco_sock_accept will eventually executing the next line of accept() in user program (printing the message). But the accept() returns earlier than the sco_sock_accept() as the following message. hci_event_packet: hci0 evt 0x4 <== the SCO connection request comes !!!! hci_conn_request_evt: hci0 Connection request: EE:E9:63:67:11:00 type 0x0 sco_connect_ind: hdev hci0, bdaddr EE:E9:63:67:11:00 hci_conn_add: hci0 dst EE:E9:63:67:11:00 hci_usb_notify: hci0 evt 1 hci_conn_add_sysfs: conn d45db800 ....
