1. Have any USB flash drives or external drives worked on your computer?
2. Which operating system is installed on your computer?

Method 1:
You may try to run the Fixit.
Hardware devices are not working or are not detected in Windows

If you are using Windows 7 you may follow the methods mentioned below.
Method 2:
Run the hardware troubleshooter and check what happens.
Open the Hardware and Devices troubleshooter
Method 3:
You may check under diskmgmt.msc, if the USB drive has been assigned a drive letter or not. If not, then try assigning one and check. Follow the steps.
a) Open Computer Management by clicking the Start button, clickingControl Panel, clicking System and Security, clickingAdministrative Tools, and then double-clicking Computer Management. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

b) In the left pane, click Disk Management.

c) If it the flash drive recognizes in the disc management and if there is no drive letter assigned, I would suggest you right click on the drive and assign a drive letter.

d)  Right-click the drive to change, and then click Change Drive Letter and Paths.

Do one of the following to assisgn drive letter.

  • To assign a drive letter if one has not already been assigned, clickAdd, click the letter that you want to use, and then click OK.
  • To change a drive letter, click Change, clickAssign the following drive letter, click the letter that you want to use, and then clickOK.
  • To remove a drive letter, click Remove, and then clickYes to confirm that you want to remove it.

b. To open device manager, type devmgmt.msc in start search box and hitEnter.
c. Check if the device drive is listed.

Method 5:
As all the hardware devices have drivers associated similarly USB devices also have it. Sometimes proper drivers do not get detected after the initial installation so reinstallation of the drivers helps resolve the issues.
You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps:
a) Click Start, and then click Control Panel.
b) Click System and Maintenance, click System, and then click Device Manager.
Note: If Control Panel is in Classic View, double-click System, and then click Device Manager.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
c) In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.
d) Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.
If you still face the same issue then you may check for the updated USB device drivers using windows update. Refer to the following link for assistance.
If the issue sill persists I would request you to check for chipset driver updates which you can get at the manufacturer website. The chipset drivers normally incorporate USB controller drivers as well.

Hope this helps.
