I'm helping out with a project for an embedded device that only has USB and no serial. This device is running Linux.

These days, when we need to connect to a serial port on a device we typically use a USB to serial adapter (on something like a phone system or a load balancing device, etc). I would like to know if it is possible to have the host device behave as though it were a serial adapter, thus removing the need for one. Given the nature of USB, is this approach even necessary?

To recap, I would like to be able to connect a single A-to-A USB cable from my workstation (be it windows or linux) to this device, for the purpose of administration (especially initial setup), using minicom, putty or hyperterminal.
