Use with USB to serial converter
Could I use this port with a USB to Serial adapter as another UART port? I currently require 4 UART ports but can only use the 3 dedicated UART ports to connect to non-PC devices. A fourth would be great!

The USB Serial lib will enable mbed as a serial Device for a Host PC. The typical USB-Serial adapters (eg FT232 or PL230X) also need a USB Host to convert USB into UART serial. These devices would require mbed to serve as USB host and they need a special driver for the specific adapter hardware. So currently this is not an option. Additional UARTs on mbed may be implemented as a software bitbang UART. There is some code available on the site. You may also want to look at this SPI to UART bridge.

You are not alone with this problem, see http://mbed.org/forum/mbed/topic/4006/
I also face this issue of USB but with the help of your post, I completely understand about this. I also have a website which provides you support like Gmail Customer Support to solve the queries of the user who face trouble in any of the email accounts. https://mailhelp.net/
