This program detects how many ttyS# available in the "/dev", and reports to next avaialable device to caller, udev program.
It searches from ttyS0 - ttyS63. If there is no available slot for Megawin USB Virtual COM, it will use ttyS64 as its
default device name.  This program also writes a device Rules, MwUsb2Com.rules, in the "/etc/udev/Rules.d".
