This is not as trivial as serial communications.

Read these articles to get an idea:

Solution 1

You don't do this. You're trying to treat the USB port the same as a serial or parallel port. You can't do that.

USB is a BUS, not a port. You talk to the devices that are attached to USB, no to the port itself.

How you do that depends on the device you want to talk to and the interfaces it exposes, normally through some device driver.
