Not sure what kind of peripherals you have in mind, but they generally
won't get ttyUSBn addresses, unless they're USB-serial converters,
which contain chips meant to provide a serial / TTY interface to the
system.
In any event, I'm pretty sure that the system will assign an available
address, generally independent of the port, unless you have a udev rule
telling it otherwise.
