fix(third_party/bluetooth): fix bugs in USB host BT HCI drivers

2026-04-21T02:05:15Z

NimBLE (nimble-1.6.0/ble_hci_usbh.c): - fix hci_read_callback: pass full buffer to hci_h4_sm_rx in one call instead of splitting type byte and payload into two calls - fix ble_transport_to_ll_cmd_impl: use struct ble_hci_cmd for type-safe length calculation instead of raw byte indexing - fix ble_transport_to_ll_acl_impl: gather mbuf with os_mbuf_copydata and issue single usbh_bluetooth_hci_write; the old per-segment loop violated USB Bluetooth class bulk transfer requirements - fix unused-parameter warnings in run/stop callbacks Zephyr (zephyr_bluetooth-2.7.5/ble_hci_usbh.c): - remove unreachable fallthrough comment after return statement - restore ISO payload length check (was commented out); use inline mask (& 0x3FFF) per BT Core Spec v5.x Vol 4 Part E Section 5.4.5 - fix bt_usbh_send error code: 255 -> -EIO - guard bt_hci_driver_register with static bool to prevent duplicate registration on USB reconnect - fix unused-parameter warnings in run/stop callbacks

fix(bluetooth): Correct HCI packet type from SCO to ISO in USB host.
