I had this problem with my Sprint Mogul and now with my Sprint Touch Pro. I think it started when I installed XP SP3, but I'm not 100% sure. The Mogul is running No2chem nuePre3 and the Touch Pro is stock.

When I first plug the USB cable into my phone everything syncs fine, and I can see the phone's files with either the Explore button in ActiveSync or by clicking on Mobile Device with Windows Explorer. After a half hour or so, I can't explore it until I disconnect and reconnect again.

After the same time period, even though the ActiveSync wheel spins as though it's synchronizing, nothing really gets updated. This bit me yesterday, as I changed the reminder time of an appointment, but it didn't get updated on the phone.

I have the USB to PC settings to "ActiveSync (Sync with Outlook)" checked and "Enable advanced network functionality" unchecked. My firewall settings allow all four ActiveSync processes as exceptions. Since it works for a while, I assume it's set up correctly.

Any ideas how to get this fixed?
