Well theirs two usb ports in front of tower and theirs several in back of tower how know which one two use none of the front ones do anything please help, thanks
You should be able to use any of them. You will most likely need to install the driver for your device
SOURCE: dell precision not recognising usb 2.0
sounds not, some of the older systems only have 1.1, Usb 2 is not all that old (about 2-3 years).
you can upgrade to USB2 bu adding a USB2 PCI card to your system, this would give you some ports on the back and it may be possible to link the ports on the front to the new PCI card to upgrade those as well (depending on how they are connected to the mobo)
you can get USB2 cards with a Pin header which would allow for a pin block connection.

It does sound like your ports on the front might be bad. They usually connect to a seperate port on the motherboard than the rear ones, and I have seen devices short out the front ports, such as a USB music player.
You can remove the ports on the device manager, and they should come back ok, without worry. However, I doubt that is going to help the front ones. I think you have a hardware problem.
If that is the case, the easiest solution is to get a USB hub, and run a USB cable from the rear, to the front of the computer.
SOURCE: none of my usb ports work. Help!
SOURCE: Have a dell optiplex gx520. Little cousins broke
take a good look inside cause when you removed the front usb you probably removed the front panel buttons too ..Plug them back and will work ..
The fact that it worked is probably why you never seen it ..It does not need the button to be connected in order to work ..the start only kicks it on ..
If this button is damaged ..you can go to bios and look if it has other alternatives fro starting ..(select to start on a set time ..or look if it is capable to start from the keyboard or on mouse double click ..some computers have this option ..for dell i think only to start on a certain hour it is available ..but if you damaged the front button is still an option ..you can also make it sensitive on the ac power ..and if the button is damaged it will start when you plug it in the inlet ..
You may actually try this ..cause unless you plug the button back ..you will not have a way to start it ..so ..try to see if it is set to react on power ..just remove it from the back and place it back ...if you are lucky will start just like it restarts when there is a power fluctuation ..
if not..you need either to reconnect the front panel ..or look on the manual ..and see teh exact pins for the start button ..and short them with a jumper untill it starts ..and make changes in bios ..and use teh keyboard or the mouse or the alarm start until you replace the button or the case...
No, it isn't hard.
Wrapping your mind around Quantum Mechanics, and String Line theory, is a little tough; though. lol!

Will make sense in a moment.
The front of your computer is the Front Panel.
Those are Front Panel USB ports.
On the motherboard are USB headers.
Small rectangular shaped pieces of plastic, that have contact pins sticking up.
EACH USB header will support TWO USB ports in the Front Panel.
Therefore; there will be two cables coming from two USB ports, in the Front Panel; and connect to ONE USB header on the motherboard.
IF, you feel the contact pins in the USB ports in the Front Panel, may be Touching each other; I strongly advise disconnecting the cables TO them.
Disconnect from motherboard.
Why?
Because if they touch each other, it will short the USB header out; on the motherboard.
This = No.
Then just use the USB ports on the back of the computer.
!O_O!
This is to save money, Mark; and save your computer.
Going further; If there are enough funds available, then I suggest replacing the Front Panel I/O/USB/Audio Control Panel Board,

Connect desktop to laptop to do what?
For USB port availability? IMHO that is like shooting yourself in the foot.
Also, how do you propose to accomplish this?
The USB ports in the Front Panel, are for ease of accessibility.
(As the young tyke has found, lol!)
Connecting a laptop greatly detracts from this.
Jus sayin'.
