Can't Recognized iPod device after upgrading to iTune 7 / 7.0.1

After upgrading to iTune 7 (and later 7.0.1), my iPod Video 60G (firmware 1.2) has been having problems getting recognized by my desktop.
Symptoms:
- Device manager in Windows 2000 reports the device as an Unknown USB Device
- The iPod won't get recharged nor sync'ed.
- The "Do not disconnect" screen won't appear on the iPod.
- Since Windows can't recognize my iPod at all, of course I won't be able to see it in iTune.
I plugged the iPod to my Dell laptop and got it recognized and recharged properly though.
After poking around for a long time, I figured that if I disable the USB 2.0 Enhanced Host Controller on my desktop (thru the Device Manager), I can finally get the iPod recognized properly. Problem is, now it takes forever for me to sync my iPod (USB 2.0 disabled, so I'm stuck with the slow USB 1.1)...
I noticed that after upgrading to iTune 7, the display backlight on the iPod is kept on (though dim). If I remember correctly, on older versions of iTune, the backlight is completely off. I'm suspecting whether the extra current draw required by the dim backlight is screwing up my desktop USB....
Anybody from Apple gonna look into the issue and consider turning the backlight back to off in the next release??
  Windows 2000  

I have no problems on my Dell laptop... I'm having problem with my 4-year old non-brand-name desktop only.
... which is kinda abnormally 'cause normally you would expect USB 2.0 power problems on laptops only. Btw, I've got the latest drivers installed already for the chipset and Win2K etc...
What's more interesting... is the fact that on older iPod firmware, everything was running just fine... upgrade to iTunes 7.0 and boom... I'm having problems. And, it's not recognized at the Windows USB device recognition level, so I think we can isolate the problem source to the iPod firmware upgrade.
Seriously... my bet is on the extra power drain from the backlight being left on during USB connection...
Guess i'll have to stick with slow USB until Apple has a new firmware...
This latest upgrade is generating a lot of unhappy customers...... and the sad thing is, Apple did a bad job in backward compatibility and made it extremely difficult to downgrade to an older version of iTune / firmware.... Apple better get these fixed asap...

  • Ipod died after upgrading to itunes 7 and ipod 1.2

    So i upgraded my itunes to the new version and then i upgraded my ipod to 1.2. Then after restarting the computer i plugged the ipod in and let it update. Itunes freezes up and then won't recognize my ipod so i couldn't safely eject it. I unplug my ipod manually which gives me the exclamation sign then it just died. I couldn't turn it on at all. The screen is just dead and the hold button is not on. Anyone have any ideas?

    I have the same problem but this only happens on my computer. It works fine during the most of it but when i use another program that makes a sound- weather it be a message noise or a game etc. it starts to skip and wont stop untill i stop the iTunes and start song again. This didnt happen with the previous version of iTunes.
    Any advice??

  • No artwork visible in iPod 20GB after upgrading to iTunes 7

    I have a iPod 20GB with colour display. I had updated artwork for all music on the iPod using iTunes 6. And now I have just upgraded to iTuned 7, and lo! all the artwork has disappeared from iPod. I can continue to see all the artwork in iTunes though, which means it is there in iPod too, but it is not visible in the iPod.
    I have tried most suggestions (unselecting "display artwork in iPod" & selecting it back, rebooting iPod, etc, etc). I have 9.5GB of songs already which makes it quite impractical to completely restoring the iPod since I have no backups of the songs.
    Please suggest something. AFAIK it is either a bug with iTunes 7 or a new iPod updated for iTunes 7 needs to be released. Own up Apple

    Maria,
    Apple's policy is clear: iTS purchases can be downloaded only once.
    Have a look at this article in the Apple Knowledge Base for some ideas on how to find your missing music.
    If you're not able to find the music, at their discretion Apple has made one-time exceptions to the "one download" policy. You can ask for an exception by submitting the form at the bottom of this page:
    http://www.apple.com/support/itunes/store/backup/
    Good Luck! But whatever the response from Apple, remember:
    Your music is valuable - please back it up!

    What is the exact wording of the error message you receive?
    Has your iPhone been jailbroken or modified to work with other

    Hi iTunes-1,
    Welcome to the Support Communities!  The error message you posted indicates a possible firmware update is needed for iTunes for Windows to work with your CD drive.  
    iTunes for Windows: Updating the firmware on your CD or DVD drive - Apple Support
    http://support.apple.com/en-us/HT201852
    Having outdated firmware can cause issues using CDs and DVDs with iTunes for Windows. Firmware is a type of software stored in a chip in hardware that can sometimes be updated.Identifying drives and firmware versions
    To run CD Diagnostics, follow the steps in this document.
    After following the steps to run CD Diagnostics linked above, look at section three to find out more about your optical drive(s).
    Here is an example of what section three might look like:
    In this example there are two drives. Drive E is a Samsung DVD-ROM drive with a model designation of SD-616 that has firmware version F000. Drive F is an NEC drive with a model designation of NR-7900A that has firmware version 1.08.Updating the firmware
    If the optical drive you are using came with your computer, check with the support site for your computer for a firmware update. Typically you will need to go to the support website for the computer maker and click on a "downloads" or "updates" link, and then enter your computer model designation and operating system version to see what updates are available. Then look through the available updates for a firmware update for your optical drive. Download the updater and run it. If you need assistance applying the update, contact the maker of your computer.
    If the optical drive you are using came as a separate part (was not included with a computer), check the support site for the drive maker for a firmware update. Sometimes the manufacturer is not clear in the CD Diagnostics results. In that case, you may just have to search the Internet for the drive model designation. You can usually find out who made the drive by looking through the results of such a search. Once you have identified who made your drive, go to the support website for that company. Look for a "downloads" or "updates" link, and then enter your optical drive model designation. Download the updater and run it. If you need assistance applying the update, contact the maker of the optical drive.Verifying that the firmware was updated
    Run CD Diagnostics again.
    Examine the CD Diagnostics results. The firmware version for the drive should be the new version.

    Also, you mentioned that you have been successful burning a CD with the Windows OS.  Make sure that you have closed all software programs that can access the CD burner so that there isn't a conflict for the drive.   Sometimes chaning the burn speed from "maximum" to 8x can also help in this situation.
    I hope this information helps ...

  • I can't update my apps after upgrade to iOS 6...?

    I can't update my apps after upgrade to iOS 6

    Are you sure you have a proper Internet connection? Make sure your iPod is connected to your computer, and you have an Internet connection.
    Don't even get me started on the iPod Touch 5G, I actually own an iPod Touch 4G, and I've considered a lot about if I should get the new one. At first look, you might be sold by the features Apple has on their iPod Touch page. It has a taller screen that's a 4-inch Retina Display, has a much better camera with a flash, and comes with iOS 6 preinstalled with Siri. But the real breakthrough comes with the new connector. It's called Lighting, and it's much smaller. But if you have a dock connector that comes with some cars, and maybe a set of speakers or docking stations as alarm clocks, I encourage you not to get the new one. The usage of your old connectors requires a $30 adapter, which is a ridiculous price. And who knows how secure the adapters will be with your docking stations? I personally think Apple has crossed the line. If they are to put a new connector with their new products, they should ship with an adapter in the box, at least at first. This is why I strongly encourage you NOT to get the new 5th generation iPod Touch.
    Sorry if I went a little off-topic there, but I wanted to get my point across. For your updating to iOS 6, I reccommend you check out other discussions in the support comunity, and see what other contributors have to say. Or go on Google and search your error messages, possibly someone might've already went through the same problem as you did. I really hope this helped!

    I would try in order:
    - Reset the iPod:
    Reset iPod touch:  Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears.
    - Restore the iPod from backu via iTunes.
    - Restore the iPod to factory defaults/new iPod.

  • After upgrading the itunes, I can not find my ipad when it connects to the PC

    After upgrading the itunes, I can not find my ipad when it connects to the PC
    Before that, I can see an botton said my ipad. And then I can click it to operate my ipad

    Try this
    Go into the control panel. Add/remove programs. Uninstall iTunes, Apple mobile device service, apple application support. Then go out and redownload and reinstall iTunes and try again.
    There seems to be a glitch with a recent update and one way to overcome it is to just start over. If that doesn't work there are more in depth things you can do.

  • Ipod not connecting after upgrade to itunes 8

    After upgrading to itunes 8 my ipod (nano) will no longer connect to my computer and is not recognised by itunes. When I connect the ipod I get the windows 'install new hardware wizard' running but however I try to work through this I get nowhere. Looking at Device Manager in Windows says there are no drivers for the ipod - it has a little exclamation mark next to it.
    My wifes brand new ipod will also not connect and its straight out of the box.
    Not at all sure what to do next. The support pages don't seem to cover getting the install new hardware wizard. Any help or advice please!.

    Ben888
    Having reported this to my dealer, and them agreeing to supply a new lead to try, I had one final attempt at resetting the iPod.
    Having restored, reset and updated the iPod half a dozen times before without success, a reset as described here:
    http://www.apple.com/uk/support/ipod/five_rs/classic/
    worked and it is now merrily playing again in the car with the original lead.
    It would seem that Apple have developed another piece of spectacularly temperamental equipment........and people slate Microsoft!
    Hope it works for you as well!

  • After upgrading to itunes 7.3.1.3 I can't run the backup to dics anymore.

    After upgradeing to itunes 7.3.1.3.1 I can not run the backup any more. Also the CD burning runs very slow.
    The DVD burner run ok with other software.
    After it checks for file to be backed up it kept ejecting the blank DVD and asking for a blank disc.
    I have even replaced the DVD drive with drive from another computer.I also reinstalled ITUNES once-- It ran as a repair during the install.

    I have used this same DVD Burner to backup my list from within iTunes before. I did this back in June just after I purchase 30 songs. I think I was running version 7.1 or 7.2 when the DVD backup worked. If not sopport then why does their diagnostics say DVD/CD Diagnostics. Even so I have the same problem on my other PC with a CD Burner. I think Apple support sound a little like Microsoft. I once had a problem with Windows NT and had to call MS support 5 times before they said their software had a defect and issued a patch.
