The USB to Serial converter would have a chip inside.
The Linux kernel supports many of these devices already.
If your kernel has those modules built then you will not need to do anything more than plug it in.

After plugging it in ... take a look at the last lines of output from the dmesg command.

I have a USB to Serial converter that uses the Prolific PL2303 chip.
This is my dmesg output:
