USB Real-Time Library supporting multiple USB Device CDC connections

Hi there.

My name is Fonseca and I have some doubts about USB Real-Time library. Would anyone clear up my doubts please?
I´ve a development kit based on LPC1857 microcontroller. This microcontroller has two USBs (both are available in my kit), and I want to use both as Device USBS, working as CDC (I mean, I want to use these two USBs as two Virtual COM Ports).
I have spent some time reading and practicing about RL-USB library, and I coudn´t find a way to connect, disconnect, get data and put data in USBs individually, what seems that two USB management aren´t possible using RL-USB library.
Is this true? If yes, is there another library for working with two USBs as Virtual COM ports?

Best Regards.
