my Dell laptops all USB ports stop working after use a charging cable to charge phone. now no power on USB ports and no data transferring. how to fix this problem?

I have tried most of the solution from web, including
*Driver Update
*USB root hub advance option.
*Open Battery and press power button,
all most everything but still not working.
please help me.
 
Try this...

1. Go to "Control Panel" and then "Device Manager".
2. Expand the "Universal Serial Bus controllers" section.
3. Double-click on the "USB Root Hub device".
4. Now click the "Power Management" tab.
5. Uncheck the "Allow the computer to turn off this device to save power" option.
6. Click the "OK" button.

NOTE: If there is more than one "USB Root Hub device" listed, Then you will have to repeat this steps for each one of them.

7. Restart the computer and all the ports should work now.

no it's not working for anything except printer and scanner, only for self powered devices. not working for others like mice, keyboard, flash drive.

Can you please explain us how USB mice, keyboard work without power? How keyboards light and mice laser light powered without any power? I don't know how can you said this..

 
Ah. You are referring to ones that do use power. There are actually 'cheaper' ones (and older ones) that don't require what others do. I have a few laying around here.

Also, most flash drives don't need power. Unless they have a light or other display on them.
