PIC functions available with USB?

Hi Jon,
I have the M-Audio Revo sound card that I'm wanting to use as a preamp.
I've designed a circuit to give 4 additional analog inputs and was planning on using a UIRT2 to do the switching between inputs.
Does the USB-UIRT have any provisions for switch control on board?
Thanks for any info.
