Hi, What I found in net/bluetooth/hci_core.c and net/bluetooth/hci_event.c are (1) the "Flush Occured Event" (ocf 0x11) is not handled in hci_event (2) while the user socket keeps pushing the data via l2cap_sock_sendmsg->l2cap_do_send->hci_send_acl ->hci_sched_tx->hci_tx_task->hci_sched_acl Eventually it stops in hci_sched_acl when checking hdev->acl_cnt. I consider that hdev->acl_cnt means: "the number of ACL packet we can push to hci_usb". Thus, I think the possible way to handle this event is to (1) add in "include/net/bluetooth/hci.h" #define HCI_EV_FLUSH_OCCURED 0x11 (2) catch the event in hci_event_packet, and do the following (same as hci_num_comp_pkts_evt) if ((++ hdev->acl_cnt) > hdev->acl_pkts) hdev->acl_cnt = hdev->acl_pkts; (3) decrement the conn->sent by atomic_sub(count, &conn->sent); Please correct me if I am wrong.
