Computer cannot detect an Apple iPod

Computer cannot detect an Apple iPod

You attach a USB-based device to a computer that is running Windows XP. Then, you try to scan for hardware devices. However, the computer may not detect the attached device, and you may not see the device in the My Computer folder.


You may experience this problem when you are using one or more of the following devices:

- USB thumb drive
- Apple iPod
- External hard disk drive

Additionally, you may not see the iPod in the iTunes application.

CAUSE

This problem may occur if there are corrupted or incorrect keys in the registry.

Solution

To resolve this problem, delete the UpperFilters registry value and the LowerFilters registry value. These values may cause access problems. (See, How to add registry keys?)

1. Click Start, click Run, type regedit , and then click OK.

2. Locate and then click the UpperFilters registry value. This value is located in the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E980-E325-11CE-BFC1-08002BE10318}

3. On the Edit menu, click Delete, and then click OK.
Note: If you receive an error when you try to delete the registry subkey, you may not have correct permissions to edit the subkey.

4. Locate and then click the LowerFilters registry value. This value is located in the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E967-E325-11CE-BFC1-08002BE10318}

5. On the Edit menu, click Delete, and then click OK.
Note: If you receive an error when you try to delete the registry subkey, you may not have correct permissions to edit the subkey.

6. Exit Registry Editor.

7. Restart the computer.

If you remove both registry values (See, How to move registry keys and values?) and you lose functionality in a particular program such as CD recording software, you may have to reinstall that software. If this problem occurs again, contact the software vendor for help.
