No Digital Devices Detected

[dbuss]

I'm attempting to connect my computer to my new 9150. I have two laptops. One with XP Professional and one with XP Home. Both are running Norton Internet Security and I have disabled the firewall protection. The computer with XP Home has connected with no problems, even with the firewall enabled. When I try to connect the XP Professional computer, the configuration wizard detects the 9150. But, when I select the 9150 and select next to configure automatically I get a message saying No Digital Devices Detected.

Can anyone give me an idea what I am doing incorrectly?

Thank you!!!
