I thought MVista is going to release 2.2.14 with USB support so I plan to
use 2.2.14 with backport

If I am not wrong, these are the driver in host mode. I am looking for tha
API when MPC823 configure as usb slave, which can connect to PC (like Kodak
DC290 using MPC823).

Is the Slave and Host API the same? I am very supprised  if that' correct.
