 You can download code to CY7C67300 through the interface(HPI,SPI or HSS)  which is used to communicate with MC9S12XDP512.

 There are some sample codes provided without OS from Xilinx ML403 webpage "ML403 USB demonstration" section at

 For sample code go through de2_app in C:\Cypress\USB\OTG-Host\Source\coprocessor\de_app.
