Don't use such old code. Please use a current version from  CVS,  for
example CVS tag LABEL_2005_08_12_0050

This will become a major problem if you should ever have any problems
or questions.

Can it operate in device mode?

The PC is a standard USB host, and U-Boot will register itself  as  a
serial device.

You better check what your hardware allows. Using a A-to-A cable with
hartdware that is not compatible may ruin both your target board  and
the PC.
