iTunes does not recognize any devices

Hi,

I have iTunes on the home computer (windows XP). The kids have iPod Touches. We've been able to buy apps, load them to iTunes, and transfer them from one iPod to another.

I just got an iPhone 4s, and plugged it in to connect to iTunes on the computer (and transfer some of the kids apps), and it was recognized by the computer (mycomputer shows it, and windows popped up asking about 'camera connected'), but iTunes does not show it on the Device listing. I tried connecting one of the kids iPod touch, it does not show up on the Device listing either.

So, no devices show up, so I can't transfer any apps, or songs, etc from our iTunes - I'd like to be able to keep all the apps, songs etc on the computer, not on a cloud, so how do I get devices to show up again?

iTunes is up to date (10.5.2).

Any ideas? thanks!

 

I found this, how to restart the Apple Mobile Device Service, and now my iTunes recognizes the devices:
