If you use a symlink I'd suggest you create a file called 
/etc/udev/rules.d/10-local.rules and put something similar to the 
following in it:
BUS=="usb",KERNEL=="ttyUSB*", SYMLINK+="ttyS0", GROUP="uucp"

my only concern is /dev/ttyS0 through /dev/ttyS3 are generally the 
serial ports on the machine.  Of course they may not exist so you might 
just want to delete them first.
