-i shorted the wires of a 2.0 usb external wifi adapter cable
-i got an over voltage warning and the device shut down
-when i restart the computer the the usb ports , cam and bluetooth are not working
(-i try a live ubunto cd and it confirms that this is not a software problem
-the usb ports have power

Welcome to the Community Forums.
I would assume that there is also a USB port on the other side next to the CD drive. You can try to check how it goes with the live media.
Removing the RTC battery and internal battery to press the power button to drain may help in a degree if the coin cell is not soldered. This may need to be checked further on a board level if there are skilled tech in your area that can trace the issue.
Just to set expectations, even if you are able to check the affected part on the motherboard, finding a part to replace it would still be a challenge. Service centers may also ask labor charge just for checking and we are not sure they would be doing board level volt mapping on this than just replace the entire motherboard.
Update us how it goes for you best.

Thank you for reply
Unfortunately the port next to the cd drive also does not work , but the "USB Audio SD Card Reader Board" works fine
I suppose that the circuit than contain cam bluetooth and usb ports is affected , but i can't find any mapping for this motherboard

OEM schematics are usually not for public so it would be a challenge searching online aside from mapping it further. Another challenge is finding the replacement chip if ever you can isolate it on the board.
These factors would urge users to instead replace the entire board consider the cost and issues on board repairs saving time.
