When the module sends bursts of data, sometimes a deadlock happens in the hso driver when the tty buffer doesn't get the chance to be flushed quickly enough.
Remove the endless while loop in function put_rxbuf_data() which is called by the urb completion handler. If there isn't enough room in the tty buffer, discards all the data received in the URB.
