Computer has six serial port, all come from where? Turn directly to the CPU, USB, and dmesg | grep tty look at kernel boot print

Thanks to reply, 6 a serial port is a physical computer interface, and a 4 g card module, take up a few USB turn out a serial port, the problem here is to use the dmesg | grep tty can only print out ttyS0 ~ 3, there are several USB turn out a serial port, I want to find where to modify the configuration, all physical interfaces to recognize, do not know to have described clearly?
