First, make sure your iPod is fully charged and then toggle the Hold switch on and off.
Reset, Retry, Restart, Reinstall, Restore
Go through the 5 R's of iPod troubleshooting, which will often solve your issue. If you're still experiencing the issue after going through each of the steps, then continue for more suggestions.
To determine if your iPod syncs via USB or FireWire, check the table in the Additional Information section below.
Tip: If you are using Windows XP and have recently installed a Service Pack, check the Device Manager. Click the Start menu and click Run. Type "devmgmt.msc" and click OK. If no devices appear in the Windows Device Manager, go here.
Still can't see your iPod?
Several things could keep iPod from appearing in iTunes or Windows Explorer. The most likely causes are listed below-you'll find information for both USB and FireWire (IEEE 1394) iPod connections. Check each one starting from the top of the list to see if that is what's keeping iPod from appearing.
Make sure your computer meets the iPod system requirements
Make sure that your computer meets the system requirements to use iPod with Windows.
If your iPod displays an exclamation point folder or sad iPod icon
If your iPod displays a folder with an exclamation point icon or a sad (unhappy) iPod icon on its screen, or if your iPod doesn't appear in iTunes or My Computer, follow these instructions to resolve the issue.
Charge the iPod and make sure it is getting power
Your iPod must have enough of a charge for your computer to recognize it. Connect your iPod to its power adapter or to a high-power port on your computer to charge your iPod if the battery is depleted. If your iPod is connected through FireWire but isn't getting power from the FireWire bus, your computer may not recognize it.
Secure the iPod's connections
Make sure that there is nothing physically inside or blocking your computer's USB (or FireWire) port, and that the cable connections to your iPod and computer are secure.
Note: If you're using an iPod shuffle (Second Generation), make sure the iPod is inserted securely in the iPod shuffle Dock.
Restart your computer
Sometimes simply restarting your computer can resolve issues.
Connect iPod to a high-powered USB port
If you're connecting an iPod, iPod mini, or iPod shuffle to your Windows computer, make sure that you're connecting it to a high-power USB 2.0 port on your computer.
If you're connecting the iPod to a Windows laptop computer through USB, connect the laptop to a power outlet before connecting your iPod. Also, see iPod not recognized when connected to Windows laptop over USB to be sure that your USB ports are supplying enough power.
Typically, USB 2.0 high-power ports are located directly on your computer. Try connecting your iPod to another USB port on the computer.
Avoid connecting the iPod to a USB hub. Connect the iPod directly to a USB 2.0 port on the computer. If a hub must be used, make sure the hub is USB 2.0, and that it has its own power supply. Also, make sure the hub is connected to a high-power USB 2.0 port on your computer.
If the issue persists, try disconnecting other USB devices from the computer such as printers, cameras, scanners, external hard drives, and USB hubs to determine if there is a conflict in the USB chain.
Check whether your iPod's cable functions properly
Make sure that you are using the cable that came with your iPod. Some third-party cables may not work properly with iPod.
Make sure that nothing is in or blocking your computer's USB or FireWire port.
Check the connections to make sure that the cable is completely plugged in.
Try another known-good FireWire or USB through Dock Connector cable if available.
If swapping out your old cable for another resolves the issue, then your original cable should be replaced.
Place the iPod into Disk Mode
Try placing the iPod into disk mode to see if it is recognized by iTunes, or My Computer.
Check which format iPod is in
iTunes for Windows only recognizes Windows-formatted iPods. You cannot use a Macintosh-formatted iPod with a Windows PC. To learn for which platform your iPod is formatted, follow these instructions.
Check whether your computer's port functions properly
If another FireWire or USB port is available on your computer, try connecting your iPod to it.
If your computer recognizes your iPod after trying a different port, the original port could be faulty.
Note: iPod will not automatically wake up if you connect it to a 4-pin FireWire port. You must press the Select button (the wheel's center button) on the iPod to wake it from sleep.
Check if Windows confuses iPod with network drive
If the drive letter after iPod ("E" in most cases) is mapped to a network drive, both Windows Explorer and iTunes may exhibit strange behavior in relation to the iPod (including preventing iPod from appearing. See "Windows confuses iPod with network drive and may keep iPod from mounting or songs may seem to disappear" for more information.
Your USB or FireWire card isn't recognized by Windows
Make sure that Windows recognizes your USB or FireWire card. Follow these steps to find out if Windows sees your card.
Third-party software may be causing conflicts
Some third-party software (such as security software) may prevent your computer from recognizing your iPod.
Try adjusting the settings of such software, or temporarily disabling it, to see if that resolves the issue.
Also, try booting Windows to Selective Startup mode to disable any third-party startup programs and services, and isolate which software may be causing the issue.
Install or reinstall iTunes
Download and install the latest version of iTunes.
In some cases, you may need to completely uninstall and reinstall iTunes.
Make sure FireWire card is a WHQL-certified IEEE 1394 card
Only certain iPod models sync via FireWire. Refer to the table in the Additional Information section to make sure your iPod can sync via FireWire.
If you have a FireWire (IEEE 1394) card installed in your computer and are using it to connect your iPod, make sure that the card is Windows Hardware Quality Labs (WHQL) certified. If it isn't, your iPod may not be recognized, or you may not be able to send music to the iPod.
If you're not sure about your card's WHQL certification, check the inbox material that came with your FireWire card or contact the card's manufacturer. You can view a list of WHQL-certified cards on the Windows Hardware Compatibility List website. To view this:
Go to the Windows Hardware Compatibility List website.
Click on the link that corresponds with your Windows Operating System to view the compatibility list.

USB hard drive is a portable external storage device that works just like a conventional hard drive. The device is simply plugged into a USB port on your computer as you would connect a flash drive. Unlike a flash drive, however, a USB hard drive can store a much larger amount of data. If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.

Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely. Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7). The USB device should be listed as "removable disk" once it is plugged into the computer. If it is not listed among the available drives on your computer, proceed to the next step. Ensure that the data cable is working properly. Try another USB cable if you have one available. Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive. Reboot the computer if the USB hard drive is still not recognized. Plug the USB cable into another USB port and check to see if the device is detected. If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port. If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem. Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager." For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter." Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives." If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears. The external hard drive may have been detected but the device is not working properly. If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced. Hope this helps.

Your iPod must have enough of a charge for your computer to recognize it. Connect your iPod to its power adapter or to a high-power port on your computer to charge your iPod if the battery is depleted. If your iPod is connected through FireWire but isn't getting power from the FireWire bus, your computer may not recognize it.
Secure the iPod's connections
Make sure that there is nothing physically inside or blocking your computer's USB (or FireWire) port, and that the cable connections to your iPod and computer are secure.
Note: If you're using an iPod shuffle (Second Generation), make sure the iPod is inserted securely in the iPod shuffle Dock.
Restart your computer
Sometimes simply restarting your computer can resolve issues.
Connect iPod to a high-powered USB port
If you're connecting an iPod, iPod mini, or iPod shuffle to your Windows computer, make sure that you're connecting it to a high-power USB 2.0 port on your computer.
If you're connecting the iPod to a Windows laptop computer through USB, connect the laptop to a power outlet before connecting your iPod. Also, see iPod not recognized when connected to Windows laptop over USB to be sure that your USB ports are supplying enough power.
Typically, USB 2.0 high-power ports are located directly on your computer. Try connecting your iPod to another USB port on the computer.
Avoid connecting the iPod to a USB hub. Connect the iPod directly to a USB 2.0 port on the computer. If a hub must be used, make sure the hub is USB 2.0, and that it has its own power supply. Also, make sure the hub is connected to a high-power USB 2.0 port on your computer.
If the issue persists, try disconnecting other USB devices from the computer such as printers, cameras, scanners, external hard drives, and USB hubs to determine if there is a conflict in the USB chain.
Check whether your iPod's cable functions properly
Make sure that you are using the cable that came with your iPod. Some third-party cables may not work properly with iPod.
Make sure that nothing is in or blocking your computer's USB or FireWire port.
Check the connections to make sure that the cable is completely plugged in.
Try another known-good FireWire or USB through Dock Connector cable if available.
If swapping out your old cable for another resolves the issue, then your original cable should be replaced.
Place the iPod into Disk Mode
Try placing the iPod into disk mode to see if it is recognized by iTunes, or My Computer.
Check which format iPod is in
iTunes for Windows only recognizes Windows-formatted iPods. You cannot use a Macintosh-formatted iPod with a Windows PC. To learn for which platform your iPod is formatted, follow these instructions.
Check whether your computer's port functions properly
If another FireWire or USB port is available on your computer, try connecting your iPod to it.
If your computer recognizes your iPod after trying a different port, the original port could be faulty.
Note: iPod will not automatically wake up if you connect it to a 4-pin FireWire port. You must press the Select button (the wheel's center button) on the iPod to wake it from sleep.
Check if Windows confuses iPod with network drive
If the drive letter after iPod ("E" in most cases) is mapped to a network drive, both Windows Explorer and iTunes may exhibit strange behavior in relation to the iPod (including preventing iPod from appearing. See "Windows confuses iPod with network drive and may keep iPod from mounting or songs may seem to disappear" for more information.
Your USB or FireWire card isn't recognized by Windows
Make sure that Windows recognizes your USB or FireWire card. Follow these steps to find out if Windows sees your card.
Third-party software may be causing conflicts
Some third-party software (such as security software) may prevent your computer from recognizing your iPod.
Try adjusting the settings of such software, or temporarily disabling it, to see if that resolves the issue.
Also, try booting Windows to Selective Startup mode to disable any third-party startup programs and services, and isolate which software may be causing the issue.
Install or reinstall iTunes
Download and install the latest version of iTunes.
In some cases, you may need to completely uninstall and reinstall iTunes.
Make sure FireWire card is a WHQL-certified IEEE 1394 card
Only certain iPod models sync via FireWire. Refer to the table in the Additional Information section to make sure your iPod can sync via FireWire.
If you have a FireWire (IEEE 1394) card installed in your computer and are using it to connect your iPod, make sure that the card is Windows Hardware Quality Labs (WHQL) certified. If it isn't, your iPod may not be recognized, or you may not be able to send music to the iPod.
If you're not sure about your card's WHQL certification, check the inbox material that came with your FireWire card or contact the card's manufacturer. You can view a list of WHQL-certified cards on the Windows Hardware Compatibility List website. To view this:
Go to the Windows Hardware Compatibility List website.
Click on the link that corresponds with your Windows Operating System to view the compatibility list.
Select your Operating System build, and then from the Product Categories pop-up menu, choose 1394 Controller.

How To Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.

The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.
