Quick Answer:

No, unfortunately P.I. Engineering does not offer any product which will allow you to plug a USB device into a PS/2 port.

Further Details:

PS/2 ports have been around for quite some time now, and many of the newest computers are shipping without PS/2 ports and are instead offering USB connections.

With the markets embracing the convenience of USB connections and moving away from the outdated PS/2 style of connection, it is unlikely that P.I. Engineering will ever produce a device capable of converting a USB style of connection to a PS/2 style of connection.
