In case it will be useful to others, I'll mention here that the English translation of the message shown on the device in the screenshot is:
Unknown USB Device (Device Descriptor Request Failed)
@andresarre If you unplug the Mega 2560 Wi-Fi board from your computer and then select Action > Scan for hardware changes" from the Windows Device Manager menus, does this "Dispositivo USB Desconhecido" item disappear from the Device Manager tree?
It is possible for a short or external circuitry connected to the Arduino board to put the CH340 chip on the Mega 2560 Wi-Fi board or USB controller of your computer into a dysfunctional state, causing this type of symptom.
Make sure the board is not sitting on anything conductive that could short the contacts on the bottom of the board. Make sure there isn't any conductive debris (e.g., strands of wire or component leads) on the board or on the surface the board is sitting on.
If you have a shield or any external circuitry or components connected to your Arduino board, try this experiment:
Disconnect the USB cable of the Arduino board from your computer.
Disconnect any shields, modules, external circuitry, etc. from your board.
Connect the Arduino board to your computer with a USB cable.
Now check Device Manager again. Is the serial port of the board recognized as expected?
This experiment will determine whether the upload error was caused by interference from your external circuitry. If so, you can then focus your attention on identifying the specific problem with the circuit and resolving it.
I find that hard to believe. The CH340 is shared between the two processors and if Windows recognises it for the one processor, it should also recognise it for the other processor; it should also give the same identification in Windows Device Manager.
I concur. The problem is probably caused either by the board being defective or having suffered permanent physical damage. I recommend you carefully review what you were doing with the board the last time it was in a working state. You may be able to identify the cause of the damage and in this way profit from the mishap by gaining knowledge that will allow you to avoid subjecting boards to the same conditions in the future.
Unless you have the right tools on hand and the skills to use those tools, repair of the board will not be feasible. I suggest you attach a note to the damaged board describing what is wrong with it and put it in your electronics salvage bin. Then purchase a replacement board.
Nah , I think that so , i have the same as u , I tryed every possible way to fix but no solution , the problem is cuzed by windows 10 ,I tested the board with out any drivers have installed in differnt pc with windows 11 it worked just fine, when i have retested it in other device with windows 10 it didnt work
