[xv6700ft]

I'm having problems syncing my xv6700 with Windows Mobile Device Center. I'm running Vista Ultimate x64. I downloaded the updated USB driver from Microsoft. When I connect, I hear the USB recognition sound. Then I hear another sound and WMDC starts the connection process but then disconnects. It stays connected for about 5 seconds. It does this every time. I have uninstalled WMDC and the driver and reinstalled. The same problem occurs. I am running the clean and simple AKU 3.5 for any Apache. I've tried to connect with RNDIS enabled and also the serial way using the USB toggle application. It only gets the brief connection with RNDIS. I don't have any firewalls other than the Vista firewall. I have tried disabling that and defender with no luck. I've searched the net and this forum (along with pdaphonehome) and can't find a solution to this problem. It seems like WMDC sucks. ActiveSync with XP was much better. Has anyone had this problem and fixed it? Please help!!!!
