I had an N8 and I first connected it to my office laptop for testing and OVI can't detect it no matter what I do. In Qt Creator, it can detect the device though. Just can't install anything because the OVI can't see it. I also tried it on my personal laptop(with OVI and SDK), same.
What I did was, I installed OVI to a different pc that has no Qt SDK yet, and it was able to detect the device. So what I did in my office laptop and personal laptop was uninstall SDK first, then connected the device, OVI was able to detect it. Then I just reinstalled Qt SDK.
Now, I have another N8 and OVI refuses to detect it again.
Does that mean I need to uninstall Qt SDK if I want to use a different device? So if I use 10 different mobile phones, I need to uninstall SDK 10 times as well? :S
