Nope.  That's a real, physical UART somewhere in your system...
might be a standard serial port, or an internal modem, or an IRDA
port.

You should be seeing a different device name somewhere under
the /dev/ hierarchy, for the USB-connected adapter.  Try

   find /dev -name tty\*

and see if something shows up.

If not, then I'd suspect that you may not have the proper
USB device driver(s) loaded.  You'll need both the basic
usb-serial driver, and the ftdi driver.  It's possible that
you're running with a kernel that doesn't incorporate these
drivers, either built-in or as dynamically-loadable modules.
If that's the case, the device will show up in "lsusb" but
it won't be accessible or usable - there will be no entry
for it in /dev.
