Windows XP stopped recognizing ipod

After initially being able to sync about 2000 songs on my ipod 3.1.1, now I get nothing when plugging it in to any USB hub. It works fine on my wife's mac. What the **** is going on?
I've tried reinstalling itunes. I've tried uninstalling and reinstalling my USB drivers. I've tried disabling enhanced USB controllers. I've tried unplugging it for 20 min. I'll keep trying to not throw it out the window.
Sometimes it says Unknown Device. Sometimes it says nothing, and lists it as a composite device in hardware mananger. Itunes Diagnostics cannot find a connected ipod. it fails sync tests. It does charge, but i don't use it for that in case it explodes.
Please help.

It worked randomly. What the **? After uninstalling all USB drivers, then had device mananger scan for hardware changes, I pluged in the ipod and it came up unknown. Then I unplugged it, plugged it in to another USB port, and it worked... This **** is so random it boggles my mind.

Shuffle causes Windows to stop recognizing all other USB ports!?!

When I plug my new Shuffle in to any USB Port, Windows stops recognizing all other USB drives. (this includes my internet connection and external hard drive with all music) If I disconnect the Shuffle and repower the other devices, they work normally again. I've seen this same problem on this forum and the answer did not help - here is the answer/link given the previous posting: http://docs.info.apple.com/article.html?artnum=93499
The shuffle has its own drive letter on my computer, so no conflict here AND my husband's shuffle works just fine on this same usb port and same cradle. As soon as I eject the working shuffle and place the new one in the cradle, my computer shuts down and no other USB Ports work until I unplug the shuffle and repower the others. Maybe a shuffle problem?
Thanks for your help!

Are you "eject"ing your husband's shuffle in iTunes OR are you "safely removing hardware" in Windows?

Windows eventually stops recognizing a Tek TDS2002B via USB

I wrote the software for a machine using a TEK TDS2002B via USB over 5 years ago and don't remember having a problem, but the machine is getting put back into production and they are having a problem with Windows eventually not recognizing the scope. As far as I remember, I only installed NI-VISA (4.4.1) with LabVIEW 8.6. My code, using the Tek dirivers I downloaded from NI, acquires the scope waveform via "Fetch Waveform.vi" code (once a connection has been established. A reboot of the computer fixes the problem (dunno for how long), but I want to stop the need for the reboot.
Any ideas?
Thanks,
Todd

In this topic we will discuss some of the common problems that have been observed using USB devices with LabVIEW on Windows operating systems. Many of these points are also applicable to other environments but the examples will be use the Windows 7 OS.
FAQ 1 : My USB device stops working unexpectedly.
The first thing to look at is the OS power saving options. There is a global trend towards developing "Green" electronics and energy star ratings are getting fairly common. "If its not being used shut it off" is nothing new. Cavemen learned how to bank a fire to preserve energy that would otherwise be wasted. Likewise, the Windows OS has a power saving feature to shut down power to the USB hubs when no user activity is present. In Automated systems this feature can cause problems since removing USB hub power will shut down the USB device. Solution: Use the device manager to change the USB hub Power Options.
FAQ2: I set the power options and my device connection is still unreliable: Remember, those computer USB ports are often the cheapest that can be mounted on the chassis and share the PC system power supply to supply USB Power. Most uses of USB are temporary connections like a thumb drive or a camera. These connections do not require high reliability since the user is right there interacting with it. Power surges and fault tolerance at worst cause the operator to retry the data transfer. Automated systems require a bit more robustness. Solutions:
1) ALWAYS use an external self powered hub. Perform your engineering due diligence and inspect the devices specifications too- If you can't find them for that device that should clue you to seek an product from a vendor that WILL publish their specs.
2) High noise environments require the use of ferrites on the USB cable- and don't buy the cheapest cable either! The cheap ones are poorly shielded.
3) PROTECT the HUB connections- If you have a USB2.0 device and Joe User plugs in a 1.0 device in a open slot managed by the same hub- Bingo every port on the hub may back convert to USB1.0. WORSE there are a lot of damaged or marginally engineered USB devices out there. Joe User's device may cause power fluctuations when it is inserted or removed from the hub just don't let it happen!
FAQ3: I am testing USB devices and the OS can't find them anymore.
This is a Plug-n-Play feature that deserves some exposure. When you connect a P-n-P device the OS remembers its serial number in a HKEY (Hive-Key) registry entry. This is helpful when (for example) you want a specific instrument, Say an NI-USB-6008, to show up as a DAQmx Device with VISA Alias "MyDAQ1" every time it is plugged it. On the other hand, If you want to test a line of USB-Serial converters this can be problematic since the P-n-P driver will mount the first serial number as "COM3" and the next as "COM4" add infinitum until the enumerator controller in the registry and VISA recognized aliases get used up. Solution: Use the Windows registry API and the Hardware Configuration API in LabVIEW to clear unused VISA Aliases and HKEY entries. Speak with your staff IT professional about HKEY structure and possible side effects before developing a plan to edit registry entries.

Macmini stops recognizing iPod,

Hello everybody,
For no reason that I am aware of my new Macmini has stopped recognizing my iPod and my external HD. Anybody might have an idea as to why and how to correct this? Thanks

Michael, are your iPod and external HD copnnected using firewire or USB?
You might first have a look at the system profiler to see if either device is actually being recognized, just not mounting on the desktop. Go to applications/utilities and launch system profiler. With both iPod and hard drive plugged in, do either or both appear in the list under Firewire (if firewire connected) or USB (if USB connected). If they do appear there but not on the desktop, go to the finder (click anywhere on the desktop), and go to the finder menu, select preferences and ensure there are check marks against 'Hard disks' and 'CDs, DVD & iPods'.
If neither device appears in the system profiler, it means the system isn't seeing them at all, in which case the port(s) through which they are connecting may have stopped. To try and resolve that, do something called a 'PMU reset'. The PMU is the Macs power management system and is reset as follows:
- Unplug all cables from the computer, including the power cord.
- Wait 10 seconds.
- Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
- Let go of the power button.
- Press the power button once more to start up your Mac mini.
Let us know how you get on!

Windows XP stops recognizing the iPod Nano

hi
I bought my Nano in Dec 2006. Assuming it is 2nd generation. Not sure how to verify. Until now I was able to copy files from Real Player to my Nano.
Now the Nano battery charges when I connect the USB cable to the Windows XP Pro system but Real and iTunes is not able to "see" my Nano I have an unhappy child at my place
What should I do? If I have to reinstall, what should I reinstall and how can I reinstall anything when the PC doesn't see the Nano device at all?
I tried connecting the Nano to my friend's system with his working cable, still his PC also doesn't "see" my Nano.
The Nano operates normally (i.e. we can listen to the songs)
Any pointers is appreciated.
Mahesh

XP stopped recognizing iPod, iPod still works with other XP computer

I had my iPod and iTunes working hapilly on my main XP Home computer until recently. XP now beeps several times (connect/disconnect) when I plug the iPod, and the drive letter briefly shows up in My Computer with a red flag, and it comes and goes for a few minutes before finally giving up.
I uninstalled iTunes and reinstalled twice with no change.
The iPod is still recognized on 2 other XP computers that don't have iTunes (I use it as a USB drive on those machines).
I have reset the iPod a few times and no change. The iPod works well by itself, and other USB devices on the main XP machine still work fine.
I did a driver rollback to March (oldest date I could find), and I know the iPod was working fine then, and it made no difference.
I am open to any suggestion. I have been considering reinstalling XP on this machine to clean it up anyway, but the Make Recovery CD program on this machine does not work, so short of buying a new XP license, or buying a new computer, I am stuck with this one.
Thanks in advance

HP Pavilion Windows XP

I thought about that, but the iPod does not show in Disk Manager. It shows sometimes very briefly in My Computer, but disconnects immediately when it does.
The drive letter assignments on this computer are a little funky, but the iPod used to be N: and currently there is nothing assigned to N:
At this moment, it is plugged in and the computer keeps beeping with the typical USB-in and USB-out sounds every few seconds.

Windows suddenly not recognizing iPod Shuffle - drive letter conflict

If you're having troubles with your PC not recognizing your Shuffle even though it used to recognize it in the past, this is just something else to consider (sorry if it's already been covered):
When I originally connected my Shuffle to my laptop on my home network, it was recognized immediately, and my WinXP OS assigned it the drive letter "I". Later, with the Shuffle no longer connected to the laptop, I was setting up my home network, and I mapped one of my shared network locations to the "I" drive letter on my laptop. The next time I plugged my Shuffle in, Windows would not recognize it. I proceeded to plug it into both of the other computers on my home network, and it was recognized immediately on both of them. So I then went back to the original laptop, disconnected the network drive mapping I had set up for "I". Once I did that, when I plugged my Shuffle back in, the Shuffle was again being recognized immediately (not surprisingly, still as drive letter "I"). In short, Windows has a memory of drive mappings made in the past, and sometimes this can produce unexpected or unwanted behavior (I would have expected my Shuffle to automatically be assigned the next open drive letter, but alas, that was not the case in my experience).
To minimize the possibility of running into this problem again (in case I do more network drive mapping in the future), I used the Disk Management utility in WinXP to change/force the Shuffle's drive letter on my laptop to be "Z" (right click on My Computer and choose Manage, then look for the Disk Management module - you probably will need Admin rights to do this, but I haven't confirmed that).
PC Windows XP Pro

Had this happening too, had a very old cable, tried a new cable and it worked great. My ipod was showing up in itunes, but not in windows (or in device manager). When I tried to use the utility to copy files from my ipod to my hard drive I couldn't do it (wonderful utility getsharepod.com). The new cable solved the problem!

TS1538 windows 7 not recognizing ipod

Neither Windows 7 nor iTunes are recognizing my iPod Classic. I followed all of the steps available in the Apple Troubleshooting section, but there does not even appear to be any sort of device in my Device Manager that is remotely iPod-esque (or USB storage-esque for that matter). What's even more troubling is that nearly 5,000 of my songs are from CDs and are only on my iPod now (It took me weeks to copy them all and I do NOT want to go through that again). Is there any way to restore my iPod without deleting everything? And if so, is there any way to copy my music from my iPod onto iTunes? I understand piracy prevention, but this is downright ridiculous. I wish I would have bought anything besides an iPod to listen to music on. :/

Windows Xp not recognizing Ipod

I tried to install my new Ipod Nano but it didn't work : during the installation, the first time I connected My Ipod, windows warned me not to intsall it. I Try to start again, but nothing happened, except the little noise, telling me a new usb is connected (but without icon). (I 've already tried the "5 R" and nothing happened). What else can I try ?

See if any of these articles help.

Windows 7 not recognizing iPod Touch

I just bought a new Windows 7 Home Premium laptop and I'm trying to connect my iPod Touch to it to put my music on my new laptop (my old computer crashed with all the music from my iPod plus more, and most of it wasn't otherwise stored), but when I plug in the iPod Touch to the computer, Windows 7 does not show it as connected. iTunes shows it is connected and it charges just fine, though.
So I guess I have 2 questions:
1. How do I get Windows 7 to recognize the iPod Touch?
2. Is there a way to transfer the music from my iPod BACK to my computer without screwing up my iPod and risk losing my music?

I have just purchased a 30gb Ipod and have tried to connect it to my computer. My wife's Ipod has no problems being recognized, and neither did mine after a few tweaks. Now it does not recognize the new ipod at all. Any suggestions on how to make this work every time would be appreciated.

hi Bill!
