I had a problem with mine - couldn't get it to read, same error - it was my palm hotsync software which was setup to look on the serial port as well as USB (I only have a USB cable for the palm). I disabled it and it worked like a charm. See if there is anything else that is using the serial port on your laptop.

Good luck!
