I have an HTC PN072 sprint based phone and have been using Sync Manager to sync to PC with outlook and all the other fun stuff successfully. However, it would appear that after some automatic driver updates pulled down by HTC driver at the end of July, whenever I plug my phone in, Sync manager gives me a 30003 error saying dont unplug your phone while its syncing. Of course I am not uplugging my phone during that time, but it thinks I am. I have uninstalled HTC Sync manager and HTC Driver and reinstalled and it only slightly improved in that it recognized my phone as HTC for 1 day, then back to unknown device the next. Sometimes Windows 7 sees my phone as HTC and other times it sees it as Unknown device. I am able to manage my pictures through it while attached sometimes, and my Local Sync app works fine through the cable (which is the original cable that came with phone). I have seen different problems at different times of plugging the phone in. The latest is that it ends up being an unknown device and windows pops up a bubble saying the unknown USB devices has malfunctioned. Anyone else having this problem, and ideas to remedy it?? Thanks
