do you have the latest version of iTunes? How old is your computer? What operating system does it have? have you tried different USB ports and cables?

also, you won't be able to restore until your computer will recognize your iphone.

OK, I'm having the exact same problem.

Running a iPhone 3G (UK on O2, not unlocked) - Windows XP Pro on a PC - iTunes 7.7.1 - iPhone software 2.0 - full battery power

Tried restarting apple mobile service and ipod service.
I can't connect so I can't upgrade the iphone software to 2.0.2
USB cable is plugged into the PC not a hub.

I plug in my iphone and it either says usb device not recognised or thinks about it for a bit and then says could not connect because of an invalid response.

It has done this since day one. I have maybe synced twice since I got the phone.

I've searched and read about uninstalling itunes and then getting 7.5 - which I'm highly reluctant to do as it's a massive hassle plus is downgrading 2 versions really the best answer??

Surely there's a better way?

Appstore won't work if you downgrade to 7.5, so i definitely don't recommend that.

The first thing i would try is hooking it up to a different computer. If it does the same thing, i'd take it to Apple, and let them either replace it, or see if they can restore it for you. If it recognizes fine, then that's a whole other story...

Hi
I had a similar problem in Vista. I extracted the Apple Mobile Device Service from the iTunes installation I downloaded of Apple. I used WinRAR to extract it and then removed the Apple Mobile Device Service and installed it again.
