usb to rs 232 and 485 converter and vise versa

First check development kit documents of the CP21XX.
for minimal implementation of RS-232 which uses only Rx and Tx you will need only a Phy. like MAX232.
also for RS-485, a line driver/receiver IC like MAX485 is all you need.
maxim and analog devices have several interface (RS232 and RS485) products.

BEST
