I have Cyclone II and I want to use "USB host/device" port to control or access the on-chip-memory.

This comment does not help me help you. The question I asked was "what type of FPGA board you have". Sure you have a board with a Cyclone II on it, but *what* board do you have? Can you tell me the name or send a link?
If it has a "USB host/device" port on it, then I'd guess you have a DE2 board. Is that right?
This project uses this interface:

In Matlab, I need the device appear as COM port.

MATLAB could probably be used to talk to sockets too, so the JTAG client/server in the tutorial I linked to would also work, or you could use the DE2 network interface and communicate directly with a NIOS II processor.
