USB ports problem
The usb ports on my Toshiba laptop are not recognizing any devices.What could be wrong?
Go to Control Panel, Hardware, Device Manager. If the USB section is yellow flagged as faulty I would delete the device and click refresh. The system should then seek the correct driver -- if problems direct the search towards Windows folder, System and System32 subfolders.
If this doesn't work, after deleting the device, restart Windows a couple of time to rearrange resources and see if the USB reinstalls itself correctly.
If the problem has occurred after a Windows update see if Toshiba site has a more recent driver pack for your computer.
