Not strictly on-FreeDOS-topic, but speaking of devices which translate USB to
PS/2, a recent project of mine has been designing a keyboard which, among many
other features, can itself connect to a PS/2 port and also accept a USB device
for input (e.g. a mouse, for example) whose data then gets forwarded to the
PS/2 port as well. I originally added this feature to allow one to record both
keyboard and mouse input and save it to a macro, but it could be used as a
USB-to-PS/2 converter of sorts as well. The first prototype is functional (in
fact, I'm typing this message on in now) and Revision B is waiting to be
soldered up for further refinement. :)
