I have a laptop running Windows XP and it will not recognize the TB when it is connected. When I plug the phone into the computer it starts chagrining but neither the computer nor the phone. I have the phone set to "Ask Me" and the default connection to Disk Drive (I tried HTC Sync as well). Under hardware the TB is not recognized at all. I have tried all my USB ports. The TB will connect to my Windows 7 machine. Any thoughts?
