Ipod Nano not showing in my computer or iTunes - have done everything?

did this just start happening out of the blue or did you install iTunes 8 and then it started?

To reset iPod, iPod (scroll wheel), iPod (touch wheel), and iPod (dock connector)

1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Play/Pause and Menu buttons simultaneously until the Apple/iPod logo appears, about 6 to 8 seconds. You may need to repeat this step.

If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.

If you are still unable to reset your iPod, use only one finger from one hand to press the Center (Select) button, and one finger from the other hand to press the Menu button.

When you reset iPod all your music and files are saved, but some customized settings may be lost. Date and time is preserved (unless the iPod reset itself because it had no power and then was reconnected to power). Other customized settings, such as Bookmarks, On-The-Go Playlists, Shuffle, Backlight timer, and so forth are preserved from the last time the hard drive turned on.

I'm having the same exact problem and have tried every perspective solution posted... and still nothing. Everything had been working fine. Then when I went to charge Nano, got the message 'USB device not recognized". Tried all posted solutions, replaced the cable, etc. Nothing. Today I had someone who has an AC charger charge the Nano with no problem. Thought that may help laptop recognize the Nano. Nope. Same situation. Any suggestions as to what I can do to once again get the laptop to once again recognize the Nano. Have uninstalled and reinstalled everything... still doesn't work and am out of options. Although I have a way of now charging the Nano, I have no way of adding new music if laptop doesn't recognize it.

so... i know it sounds too easy.
but it worked for me.

1. charge your ipod.
2. w/o turning it on first, switch the hold button
on the top of your ipod to "hold" then back off again.
3. repeat that off/on hold deal about 10 times.
4. then reset your ipod by pressing the center select button
at the same time as the menu button.
5. the apple logo should appear.
6. then try reconnecting your ipod to see if itunes will
recognize it.

silly soundin' but it worked for me after i tried everything after
updating to 8.

goodluck!!
& if it works, spread tha word.

Thanks for trying!!! I appreciate the effort. I too have a 2nd gen nano that has stopped being recognized. Tried your quick solution a couple times with no luck. Hopefully Apple figures out what's wrong as it seems to have happened in conjunction with one of the recent upgrades of iTunes.

thnx a lot for the effort i tried those options but no luck.:(

Omg You my friend are my hero. I've been going for months without being able to connect my ipod it was driving me crazy and what you said worked!! lol The simplest thing.. now i feel like an idoit.
Thanks a million

I did everything suggested in this discussion topic... and unfortunately had no luck. The ipod would recharge only with an AC adapter. Even fully charged, no luck getting the laptop to recognize it. Finally resorted to visiting the Apple store. They are more interested in selling me a newer nano then they were in identifying the problem. Told me the problem was with the dock connector at the bottom of the nano. They said this is why the laptop wasn't recognizing the nano. I'm not buying that answer, since, when docked into an AC adapter, the nano charges beautifully. The problem is when it's hooked up to the laptop that it's not recognized. This problem suddenly popped up once iTunes was upgraded.
