Usb ports not working?

USB ports not working?

• The other day I plugged my ipod touch into the family desktop to put more music on it, and it didn't show that a device was connected, it didn't even show that it was plugged in or charging on the ipod. I assumed the was something wrong with the USB cord, so I used another one, and still, nothing happened. Later on that day, I plugged my ipod into my laptop and it began charging. I also used the other USB cord, and it worked. To see if there was something wrong with the USB ports on the desktop, I plugged in several different USB cords and none of them did anything. There are 2 USB ports on the tower, and it's a compaq brand tower. The left one has always been a little iffy, but now neither of them are working, and I can't use my laptop to put more music on my ipod because it's extremely slow and downloading any music software will cause it to crash. Is there any way to make the USB ports on the tower start working again? Thanks

• Answer:

  Shut down your computer completely, unplug the power cord from the back for at least a minute (this drains the power from everything). Then power back up if that doesn't work start orb>type device manager in search box>clik on device manager>universal serial bus controllers>look for an exclamation mark>rt clik>properties>driver>update driver also under power management make sure allow the computer to turn off this device is unchecked
