yep, I've seen one N9 which usb port connections had come loose after someone dropped it to floor with cable connected. I had to do some soldering to get connections working again.

So professional fixing companies (like nokia care uses) should be able to fix it. Also possible as DIY, but connection pins are really really small though, so if you don't have really stable hands then your in trouble. There are a bit bigger usb debug connection points on the other side of the motherboard, where soldering is easier, but even that will require some tweaking.
