Just because apple mobile device support is listed doesn't mean it's going to work. It was listed in my control panel but still wouldn't work. I ended up deleting everything apple...(heck, here.....my copy paste message for the others...)
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.
