For some reasons I open can port twice (by using cyg_io_lookup), two handles one for read one for write, It works fine with serial ports,  with can ports it still works right but will cause the problem I mentioned . 
By the way, it's right about 18EA00xx , I have to send 18EA0080 to get the response.
