A device entitled Portable Device normally refers to a USB port that has not been associated with the appropriate driver.  You may also notice that on the General Tab for the device, a Code 19 is displayed with the following text: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.

The following steps resolve this issue:

  5. Right-mouse each Portable Device and select Uninstall.

  6. Once each of the Portable Devices have been uninstalled, right-mouse click your Computer Name at the top of the list and select Scan For Hardware Changes.

  7. The devices should then be automatically installed.

  8. To confirm that this issue has been resolved, reboot the computer.  Upon reboot, return to the Device Manager and confirm that the yellow exclamation marks are no longer being displayed.
