   b. click on the plus sign before “Universal Serial Bus Controllers”

   c. Find your devce in the list (sometime it will be shown as USB Mass Storage Device)

   d. Right click and update the drivers by uninstalling and reinstalling the drivers.

3. But if the Pen Drive comes up faulty then just get it replaced.



Problem 2: Pendrive detected, but not showing up in the drive list

This problem is caused when Windows fails to assign a new drive letter to the Portable Drive inserted for the first time.

1. Open Run, type “compmgmt.msc” and hit enter.

2. Now click “Disk Management” on the left side.

3. On the right side, right click on your USB Drive that appears in the disk management window and click change drive letter and paths.
