ITunes suddenly not recognizing my iPod Touch 4g

I got a new 32gb iPod Touch, 4th Generation, last week. Everything's been working fine. Then, this morning, I went to sync my iPod and iTunes didn't open automatically. I opened it manually and it hung for a few seconds then worked again but my iPod wasn't showing up. I checked in Windows Explorer and my iPod was definitely connected. To clarify, I'm using iTunes 10.1.1.4 (64-bit version) under Windows 7 Home, 64-bit.
I went through all the steps in all the appropriate KB articles and nothing worked. I tried stripping all traces (AppData, iTunes Library, registry entries, etc.) of any Apple software and reinstalling and still no luck.
I tried placing my iPod in Recovery mode and, lo, iTunes recognizes it. I figured it must be an issue with the iPod. So I, reluctantly, did a restore. Everything went fine until the point where the iPod restarts. iTunes does not recognize my iPod. So now my iPod is stuck in a factory reset state (screen with the picture of the USB cord and the arrow to the iTunes icon) and iTunes 10.1 won't recognize it. It's not showing up in Windows Explorer at this point but the Apple Mobile Device USB driver is showing in Device Manager.
I read one post where someone had success rolling back to iTunes 9 then updating to 10.1 that way. I tried this. While it didn't work, it did show me something interesting: Although iTunes 9 could not sync with my newer iPod, it DID recognize it and tell me to update.
Finally, I tried rolling back to version 7.9.2 of CoreAudioToolbox.dll. Still no luck.
Since then, I've managed to sync just fine with iTunes 10 running under a Windows XP Virtual Machine in VMWare Workstation. I've also synced just fine with CopyTrans manager, an iTunes alternative (although it's not very powerful and doesn't sync files for apps ie: Can't add videos for VLC Player). Seeing as these worked, I can rule out problems with the iPod and problems with my Windows install. It seems to be localized to iTunes running under Windows 7.
Futhermore, I've realized that I can't view the 'Devices' tab in iTunes preferences. If I click on it, iTunes just hangs and stops responding. The tab becomes highlighted, but the content below stays as whatever tab I was previously on. This specific symptom seems like something to me that might clearly indicate what trouble my iTunes is having - an overall issue with devices - but every combination of search terms that I can think of turns up nothing.
My hope is that someone here will know what this means, what files and/or registry entries I have to delete and or replace? Did I miss something when I cleared everything iTunes related out of my system before? I must have, since the issues carry over from install to install.
Many thanks in advance to anyone who can help!

How did you get the VMWare sync to work? I hate Apple at this point.

Apple will not help you fix your jailbroken iPod. Have you tried to place he iPod in recovery mode and then restore via iTunes. For recovery mode:
iPhone and iPod touch: Unable to update or restore
Next try DFU mode.

ITunes is not recognizing my iPod Touch After iTunes froze during a sync!

Okay... i was syncing my second gen iPod Touch (16gb) with iTunes and everything was going normally, until iTunes froze on my windows PC!!!
Then, i had to use ctrlaltdel (task manager) to end task for iTunes. When i restarted iTunes to try and sync my iPod Touch, it asked me if i wanted to enable syncing. I clicked yes, and then it said sync services could not find information on this device.
I had NEVER tried to jailbreak my iPod Touch, i just installed 3.0 yesterday, and sync was working perfectly. I didnt have any problems.
Please help me. How do i fix this? i looked on apple.com and they said to reinstate the Apple Mobile Device Service, which i DID. i followed their instructions to the letter, but nothing has worked. Im really scared! i payed $300 for this iPod and while everything works, it wont let me sync to iTunes!!!

OK, no need to panic. Most everything is fixable.
First off, reset your touch. Hold the Sleep/Wake and Home buttons down together until you see the Apple logo. Let go and let it restart.
Reboot your PC. When it is done, check to see if Apple Mobile Device Services are running. If they are, plug in your iPod. What happens?
Does anything pop up like a camera notification, or your PC reports it can't recognize this device?
If you get the camera notification, you will have to disable that before itunes will see your iPod. Search Support for an answer to that.
If you are still having problems, completely remove all Apple software from your computer (iTunes, Apple Mobile Device Services, QuickTime) and download and re-install iTunes.

ITunes Not Recognizing my iPod Touch after Upgrading from Tiger to Leopard

After upgrading from Tiger (10.4.x) to Leopard (10.5.0=>10.5.6), my iPod Touch is no longer recognized by iTunes 8.0.2. The iPod Touch no longer appears in iTunes' "source list" (left side pane in iTunes' GUI).
Immediately prior to that upgrade, my iPod Touch was working great with Tiger (10.4.x). iTunes 8.0.2 recognized it (listed it in sources) and always synchronized with it successfully.''
My iPod Touch is also not shown in the Finder. However, it does show up as recognized in iPhoto.
Any ideas on how to get the iPod recognized again in iTunes under Leopard?

Thanks to a posting by Jim in a different Apple Discussions (forum), my problem is now resolved. Read on for the details.
iPods & Finder. Some other postings incorrectly lead me to believe that the iPod would show up in the "Finder". Jim's posting set me straight on this.
iTunes Not Recognizing iPod Touch. Prior to Jim's posting, I had already read the article that Jim referenced (to remove and reinstall the Apple Mobile Device Service per article "http://support.apple.com/kb/HT1747").
Prior to Jim's posting, I had also read other articles in various "Apple Discussions" (forums) that suggested this recognition problem could be resolved by uninstalling/re-installing iTunes 8.0.2. Some implied that you could just re-install iTunes 8.0.2 right over the currently installed one without bothering to uninstall it.
Based on those postings, I "gambled" last night and simply downloaded and re-installed iTunes 8.0.2 (without uninstalling it first). I noticed during the installation that the Apple Mobile Device agent was also re-installed. Well, my gamble paid off! After the installation (and a reboot?), iTunes onces again RECOGNIZED my iPod Touch.

Why ITunes do not recognize my iPod Touch

Hi everybody!
I have an IPod Touch and for some weeks, I have big problems with ITunes I can not solve. Let me explain:
Initially, it worked fine. Then one day, decided that ITunes does not recognize my IPod Touch, more precisely it do not read more.
When I plug my IPod Touch, ITunes tries to read it and then a message appears saying: «ITunes can not read the contents of the IPod xxxx». Then they told me to restore my IPod to restore the original settings, I tried but it did not work either because after a while a message appears telling me that my internet connection failed while yet it works!!?!!
Then I tried to solve the problem in the tab «Help» ITunes under «establish a diagnosis» and then the test tells me that there is no IPod detected while my IPod is plugged and recognized in Windows Vista. It tells me: «ITunes could not connect to the IPod xxxx because the record is missing the match.» What does that mean??
I also tried everything in the Apple support and nothing worked. My IPod ans ITunes are up to date. I even uninstalled ITunes and any Apple product for the reinstalled everything but it still does not work.
Does anyone can help me??
I confess that I am discouraged and frustrated.
Thank you in advance!

Bonjour tout le monde!
J'ai un IPod Touch et depuis quelques semaines, j'ai de gros problèmes avec ITunes que je n'arrive pas à résoudre. Je vous explique:
Au départ, tout fonctionnait bien. Puis un jour, ITunes a décidé qu'il ne reconnait plus mon IPod Touch, plus précisémment il ne le lie plus. Lorsque je branche mon IPod Touch, ITunes essaie de le lire puis un message s'affiche me disant: «ITunes ne peut pas lire le contenu de l'IPod xxxx». Puis on me dit de restaurer mon IPod afin de rétablir les paramètres d'origine, ce que j'ai essayé mais ça ne fonctionne pas non plus car après un temps un message s'affiche me disant que ma connexion internet a échoué alors que pourtant elle fonctionne!!?!!
Puis, j'ai essayé de résoudre le problème dans l'onglet «aide» d'ITunes sous établir un diagnostique et là, le test me dit qu'il n'y a aucun IPod détecté alors que mon IPod est bien branché et reconnu dans Windows Vista. On me dit aussi: « ITunes n'a pu se connecter à l'IPod xxxx car l'enregistrement du jumelage est manquant». Qu'est-ce que ça veut dire??
J'ai aussi tout essayer dans le support d'Apple et rien n'a fonctionné. Mon IPod et ITunes sont à jour. J'ai même désinstallé ITunes et tout les produit Apple pour tout réinstallé mais ça ne fonctionne toujours pas. :-(
Est-ce que quelqu'un peut m'aider??!!
J'avoue que je suis découragée et frustrée.
Merci d'avance!

Itunes does not recognize my iPod Touch using Windows 7 - 64bit

Itunes does not recognize my iPod Touch using Windows 7 - 64bit. Is this a driver issue? Has anyone else had this problem? Is there a fix?

hi sally,
see if this user tip by Yorkwill helps:
+In the end what works is to just force the drivers on what windows thinks is a camera, i.e. to ‘update’ the device to use the correct driver. There are some hints on how to do this already listed on this forum, but I’ll try to give some more detailed information:+
+1. First off you need to have iTunes installed and the ipod touch plugged in+
+and recognized as ‘something’ e.g. digital camera (it shouldn’t really+
+matter what it’s recognized as, but it needs to be found by windows).+
+2. Search for usbaapl in the C:\WINDOWS system folder:+
+o open windows explorer (e.g. Right-click Start and then click ‘explore’)+
+o right-click the WINDOWS folder and select ‘Search’).+
+o type in usbaapl and hit Search – try to ignore the dog!+
+You should find the driver info in a sub folder of+
+C:\WINDOWS\system32\DRVSTORE e.g. C:\WINDOWS\system32\DRVSTORE\usbaapl_A65621D65F5B7507DD7B22331826547BDD2D206B+
+Remember that location (either leave the search box open or copy the folder+
+name into note pad – you’ll need it later)+
+If you don’t find usbaapl.sys, usbaapl.inf etc. then your drivers have not+
+been installed with the iTunes install and you’ll have to reinstall iTunes.+
+3. Locate the ipod-camera device:+
+o Open the device manager, e.g. using Start > Control Panel >+
+Performance and Maintenance > System > Hardware Tab > Device Manager+
+o Look for a device called ‘ipod’ - if your ipod shows up as+
+‘digital camera’ it will be under something like ‘imaging devices’.+
+4. Update the driver:+
+o Right click the ‘ipod-camera’ in device manager and click on+
+‘Update Driver’ – the Hardware Update Wizard will open.+
+o Check the ‘Install from a list or specific location’ then click ‘Next’+
+o Check ‘Search for the best driver in these locations’. Un-check+
+‘Search removable media’ and check ‘Include this location in the search’.+
+In the text box below type (or better copy and paste) the folder+
+containing the ipod driver information found in step 1 (in the example+
+above it was C:\WINDOWS\system32\DRVSTORE\usbaapl_A65621D65F5B7507DD7B22331826547BDD2D206B), +
+then click Next.+
+You should now see something like ‘Apple ipod device driver’ or so. Continue+
+installing that device. Once the driver has been installed the ipod will come+
+to life and iTunes (if you have it open) will show it.+

Some songs, which are bought in the iTunes store, will be played iTunes but not on my iPod touch. Has somebody an explanation for that? Thanks,

Some songs, which are bought in the iTunes store, will be played iTunes but not on my iPod touch. Has somebody an explanation for that? Thanks,

No, you should have Restrictions OFF.
Computer's iTunes > Preferences > Parental Preferences > everything should be unchecked.
Are the songs also on computer's iTunes?
