not sure if lpc21isp is capable of loading/running the RAM version,
maybe try the ROM version. The RAM version is to be loaded with
lpc21iap. You do not have to give a serial number.

shows that it detected the USB device? Maybe you can send the full chain
of commands you gave. Did you compile with the provided makefile with
windows?
