I have an HP DV1170EA laptop and the USB ports have stopped working. None of them work. I cannot use a mouse also. This just happened out of the blue without any warning.
I tried un-installing the USB drivers through the driver manager and re-installing them again. During the Scan for New Hardware, all the drivers were re-installed. Not able to figure out what could be the problem.

After you uninstalled all the USB in the Device manager, did you re-boot the computer. You must do this to completely uninstall. You say 'During the scan for new hardware', you don't have to scan as after the re-boot the system will simply find them and say 'found new hardware', and then tell you when it is installed 'your new hardware is installed".

I did what you said. Un-installed the USB drivers and then did a reboot. As you said, the USB drivers were installed and they appear in the Device Manager. But the USB ports still do not work. I am worried if the USB controller on the motherboard has gone bad!

What are you using to test your USB ports. Maybe that testing device is faulty.

In the Device Manager, I checked the property for all the USB Root Hubs and USB ports and it said that the device is working properly. I tested my USB ports using a USB mouse which works on other laptops properly. Only on this one, this doesnt work. Nor does the Synaptics touchpad work. So I cannot "Click" anywhere...and have to use the keyboard for navigation.

If this fails, you could save all your data and do a 'destructive recovery' back to factory settings with your HP recovery disks.
