Replacing the stock mounted usb port, that would require you some screwing, but it depends on your system. You can try look at ebay for similar model of casing or other online store.

There are some external Usb port that can be mounted on 5" bay, or try any 8 in 1 external.

I've never seen 2 front USB ports that were bad. I've seen 1 that was defective because the USB device that was plugged into it was broken off. However in that case it caused the power supply to short out and prevent the computer from powering on. Here is a link to your model:

If the USB ports on the back of your computer work then the front ones should too unless there is a connector dislodged to motherboard. All USB ports use the same circuit.

un bend it

Simple. Just solved it with advice from this site. If you see any of the gold prongs touching the side (or possibly each other) then find a thing tool and try to hook the gold prongs so they point direct upwards. how bad they get bent doesnt matter, just get them all standing up and not touching the sides. you probably cant use the port again but atleast it turns on.

With that amount of non-accidental damage, a replacement is the best option financially

well there are 2 other ports on the 360. two in front and one in back. you could buy a powered splitter to run more than two usb devices on the same hub.

you need a fireware card to connect with pc maybe dv port is not broken

If the ps2 port on the main board is broken you will need to replace the board. If this is the case and your computer has usb ports on it just go out and buy a usb mouse.

 

If the part that is broken is from the mouse by using tweezers try to gently remove the broken part from the board. if unsuccessful use the usb port with a usb mouse.
