i was having this problem with my iphone.......1st go into the control panel and then to uninstall programs and uninstall anything apple. once everything apple is uninstalled. go to www.apple.com and install the latest itunes. after the latest itunes is installed this should work. it worked just fine for my iphone. ps i had my iphone connected to my computer during the whole process.

Yep...^^

I just fixed my ipod nano problem on my own and figured I'd share as I have just spent the last 4 hours trying to trouble shoot all of Apple's problems...following everyone's tips...nothing worked until I figured it out on my own.

I'm running windows 7 and have an Ipod Nano (6th Gen). Hard drive crashed on computer. Replaced HD. Everything works fine now. Downloaded iTunes along with all other programs. Nano wouldn't show up or sync on iTunes. Said Device Driver Software was not successfully installed (some USB problems). Tried everything. Finally, I figured it out.

Disconnect Nano. Uninstall iTunes AS WELL AS

Apple Application Support, Apple Mobile Device Support, and Apple Software Update. Apple only

tells you to uninstall iTunes and reinstall..restart computer bla bla bla. I said screw it and uninstalled all Apple programs (well, the listed ones above). I hooked up my nano to my computer to make sure the device manager recognized it without anything else plugged in...and it did. I unplugged it. Reinstall iTunes and all three other Apple programs listed above will also reinstall. I opened iTunes and plugged in my nano. It started with the "installing device driver software" and I was sure

it wasn't going to work. Well, it did work. My nano showed up in the upper right bar of iTunes and synced. Unreal... I unplugged my nano and plugged in the wife's. Once again, "installing device driver software." Voila! Her's showed up and synced too. I plugged mine back it to make sure it worked and it did. I'm done. It's working. Hope these steps work for you as well.
