How to resolve USB storage device not properly detected in Microsoft Windows®

Article Summary: How to resolve USB storage device not properly detected in Microsoft Windows®

USB Storage Devices Not Enumerated

Known good USB flash drive or USB hard drives are not properly detected by the Microsoft Windows® operating system. (Issue generally seen in Windows)

Driver installation failure: Due to the fact that the drives have been confirmed as known good drives on other systems and that non-storage USB devices such as a keyboard or mouse work on the effected ports lends to the determination that the issue is one of driver installation.


In some cases, this issue can be resolved by updating the USB storage driver.

  1. Plug in your USB device. (when you open the Device Manager, you should see under "Other Devices," the USB device listed next to an exclamation point in a yellow triangle.)
  2. Move the mouse/cursor over to the USB device name so that it is highlighted. Right-click and select "Update Driver Software."
  3. When prompted "How do you want to search for driver software," choose "Browse my computer for driver software." there will be a space for typing or browsing for the location of the driver. Type "C:\Windows\winsxs" (without the quotes), and ensure that the "Include subfolders" box is checked. [it is assumed Windows files are on the C: drive.]
  4. Click "Next". there will be a warning message about the driver file not having been verified, and asking me if you want to continue. Click "Continue".
  5. At this point the driver installation should complete and the USB device should be detected and function normally.
NOTE: if the drive doesn't detect, disconnect the device, reboot then reconnect the device.
