I purchased a automotive OBDII scantool software and interface ELM327 wich needs available com ports. Everything was installed sucessfully and no conflicts in the Device Manager. I can only add an incoming com port but not an outgoing, it displays "access denied". I also noticed that while installing the bluetooth device (with the wizard) it did not show me the com ports being used on the finish page as the instructions said. Customer support has been contacted but yet to  recieve a reply. I have been researching on the internet and all I can come up with is that Windows XP Sp2 Home Edition may have issues with it. I tried installing it after a "Clean Boot" and checked for conflicts (none were found).
Hopefully I can get some help on this one
