I am a new user, although I have had a regular Q for about a year. I bought aQ9c on Monday and set it up and had activesync working fine with. It just stopped late last night. Now everytime I plug my phone in, it tells me that my usb device failed to connect and that it did not work. I did download Service pack 3 for XP and installed it, but I thought activesync had worked since then. Now when I plug the Q9c in, it still shows that the usb device is not connecting. I have changed the setting a few times, including what you the other user above had done, but it just stayed the same. I did get all of my contacts downloaded and saved, but still cant figure it out.....
