Honored Contributoraccess to usb device in serial way
I want to connect FPGA to PC with usb device, but most applications access devices by serial (COM port). Is that possible let usb device appear as an additional COM port? Thanks!

Honored Contributor --- Quote Start --- I have Cyclone II and I want to use "USB host/device" port to control or access the on-chip-memory. --- Quote End --- 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: http://mzakharo.github.io/usb-de2-fpga/ (I have not tried this code) --- Quote Start --- In Matlab, I need the device appear as COM port. --- Quote End --- 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.
