I use the Xilinx Parallel IV cable (and jp2).
You could probably hack something together for the Xilinx Platform USB
cable by mixing code from this driver (http://rmdir.de/~michael/xilinx/)
and jp2. I've been meaning to try this, but I just haven't had the time.
You could also probably hack together something based on an FTDI2232. I
bought one of these (http://www.dlpdesign.com/usb/2232m.shtml) to
experiment with but, again, no time.
Another alternative is to try something like this
(http://www.amontec.com/jtagkey.shtml) or this
(http://www.amontec.com/jtagkey-tiny.shtml), both of which are
FTDI2232-based. You might be able to mix code from OpenOCD into jp2.
