Hey, Just received my del, and I installed my Sony PEG S300 software to it.  The PDA is connected to the laptop through the USB port.  When I attempt to do a "hotsync", I receive the following error message, "Unable to initiate HotSync operation because the serial port is in use by another application".  The only other things connected by USB are the mouse and keyboard.  I had this same PDA installed on my IBM Thinkpad without a problem.  What should I do to fix this problem?  Thanks in advance for the help!
