 usb_fill_bulk_urb(port->read_urb, dev,
                       usb_rcvbulkpipe(dev, port->bulk_in_endpointAddress),
                       port->read_urb->transfer_buffer,
                               port->read_urb->transfer_buffer_length,
                       ftdi_read_bulk_callback, port);

 (can be call in the interrupt context)
 ftdi_read_bulk_callback--->
                           ftdi_process_read-->      
                                               tty_flip_buffer_push(tty);
