Ipod not recognized by computer or itunes

i had this problem with my shuffle and had it with my 7G 3rd generation nano. It does appear to be a usb problem, as suggested. i fixed it both time by go to the Device Manager (right click on my computer - properties - hardware - device manager). If your ipod is connected, you will see the apple ipod DRIVER even when you don't see the ipod in my computer or in itunes. Right click on the Apple ipod driver and uninstall it. Then your pc will automatically reinstall the driver because your device is still connected. After that reinstall happens, you should your ipod in itunes. I hope it works for some!!! I think it's almost always a usb problem. My error happens whenever I plug in my ipod when other usb devices are connected. To be safe now, I have to remove all other usb devices before plugging in my ipod.

get the ipod nano fixed

This has apparently occured with MANY people who have bought the 3rd Gen Nano. Either a) the computer is shut off wit th enano still attached, or b) the nano is removed prematurely, without hittnig "Eject" first. Try loading an earlier version of iTunes (7.4.3) from www.filehippo.com. This also seems to be a PC-exclusive issue.

Did you try a different PC?

I struggled with this issue for a while and finally found a post that helped me. Hold menu and the center buttons until the iPod turns off. Then, immediately hold the left and center buttons to pull up the iPod diagnostic menu. Scroll down to the option "Reset" and select it. My iPod was finally recognized by iTunes. Good luck :)

My ipod was getting a USB error "unknown device", and iTunes wouldn't recognize it at all.
Read somewhere that it may be an issue with USB 2.0 vs 1.0, and a USB controller called 'Enhanced Host'.

I opened Device Manager, then the Universal Serial Bus Controllers. Someone suggest uninstalling all of them and restarting, then have windows reinstall all of them.
Instead I just uninstalled the USB controller called 'Enhanced Host'. Right away windows tried reinstalling it. Then I opened iTunes and plugged my iPod in. Both Windows and iTunes recognized it right away.

I don't know why, and I don't know how, but that finally worked for me when nothing else did.

I read somwwhere that it is a USB conflict. Apparently you can unplug other usb devices presently hooked up to your computer and when you unplug the correct one your computer will recognize the ipod. I have not tried the fix yet . I think I need to recharge my ipod battery first and see if that cures the problem. Hope the usb conflict thing works for you.

Get a new usb cord. That might fix it.

I had the EXACT same problem ! All i needed to do was simply reset my ipod. it didnt take anything off of the ipod , and it completely fixed the problem. 'erad' explained how do do this on a previous post , so i wont repeat. best of luck.

I have a brand nw apple nano says made in California. I tried connecting it to my pc. I also hace an 80g classic. Wanted to syncronize the new 16g. But, it works as an mp3. Apple program did not recognize it. Tried to synch with microsoft media player. Started to recognize or so it seemed. At 70% (was very slow) both computer and ipod shut down. Now ipod does not turn on at all. Can anyone tell me how to fix?
