PC freezes when iPod Touch is fully charged

Mkay, charging without the dock didn't make any difference; the PC still freezes as soon as the iPod is fully charged.

Charging whilst iTunes is running doesn't help either; maybe I should try and see what it does with an older version of iTunes. Anyone have some other bright ideas/suggestions?

Hmm, I just noticed something. The iPod also seems to randomly wake up when it wasn't even connected to the computer (or a USB power brick). I bet if it were connected to my computer, it would completely freeze.

So what I'm getting at is this: In my first post of this thread I said that when the PC suddenly completely froze, the iPod also woke up (, but continues to behave normally). Now I've figured that the iPod can also wake up even when it's not connected to the computer. So... , I'm thinking that this random waking up is the cause of the PC suddenly freezing. And because the random waking up can happen even if it's not connected, the computer is not the one to blame. Therefore, it's the iPod's fault! More precisely, it's a bug in firmware 2.2, because I don't recall having any problems on firmware 2.1 or older versions.

In conclusion, I should try and revert back to an older firmware version. If my guess was right, the problem should be gone and then I should probably report the bug to Apple (Anyone know where I can do that? if at all possible...).

Darned, that was a bad guess... I tried out firmware 2.1 and 2.0.2 today, but it can still freeze the PC.

Reinstalling Windows' USB drivers didn't help, so there's only one thing left: downgrading iTunes. I've got some hope that this will finally do the trick, as I've read some news posts about BSODs and other sorts of issues with the latest versions of the "Apple Mobile Device Service" that come with iTunes 8. ( http://blogs.zdnet.com/Apple/?p=2270)

Now I've reverted back to iTunes 7.7 (which is the earliest version that supports the AppStore according to http://en.wikipedia.org/wiki/ITunesversionhistory)

I've finally made some progress in solving this pesky problem. I have now reverted back to iTunes 7.7. If I leave all Apple-related background services enabled (Mobile Apple Device Service, Bonjour service, iPod-service, AppleSyncNotifier, iTunesHelper and QTTask), the problem still exists.
Once I disable all services though, the problem is gone. This was also true for iTunes 8, but the difference is this: Even with all those services disabled with iTunes 7.7, the iPod Touch is still able to get its power from the computer. For some odd reason, this isn't true for iTunes 8.

If I can now pinpoint which service causes the PC to freeze, which hopefully is something iTunes doesn't need to function properly, the problem is fixed. (or at least I'll know who is causing all the trouble...) For now, I'm already happy that my iPod can charge without freezing my machine... 🙂

You're right about the random thing; at first I thought it only happened when the iPod was fully charged, but it has also happened on random occasions...

Anyhow, I actually managed to get my iPod Touch (1G) charging again, without freezing the computer. The downside is that I can't sync.

What I've done is this:
* I have moved back to the latest version of iTunes (8.0.2.20). I also have the latest firmware on the iPod Touch (2.2).
* I have disabled the following Apple services/startup-programs: iTunesHelper, AppleSyncNotifier and Apple Mobile Device
To do this: Go to Start > Run,
then type "msconfig" (without the quotes), click OK,
then go to the "Services" tab, remove the checkmark on "Apple Mobile Device",
then go to the "Startup" tab, remove the checkmarks on "iTunesHelper" and "AppleSyncNotifier",
then click OK and you'll be asked to restart the computer.
* When the computer has restarted, a window'll be shown that says you've modified your configuration... You'll probably want to check the checkbox in this window; otherwise this window'll pop up every time the computer restarts...

Now your iPod Touch should be able to safely charge without freezing the computer. When you start iTunes now, you'll get the message that says the iPod won't work because the Apple Mobile Device-service hasn't started.

I have disabled this Apple Mobile Device because I'm quite positive it's the cause of all this freezing. If you do need to sync your iPod, it's possible to enable the Apple Mobile Device-service for a while, and then disable it again.
Just do the following to start it:
* Go to Start > Run
* Type "services.msc" (without the quotes) and click OK
* In this new window, look for the "Apple Mobile Device" entry in the list; double-click it.
* Change "Startup type" from "Disabled" to "Manual"; click "Apply".
* Click the "Start" button in this window to start the Apple Mobile Device-service.
* Click OK and then close the "Services" window.
* iTunes will now recognize the iPod Touch again, but the you'll be at risk of freezing the computer...
