Good afternoon!
The question is:
With the correct connection of usb / hdmi / headphones, etc. to the motherboard, can it lose its functionality?
I will decipher the word "wrong" in this particular case - incorrectly mechanically.

usb/hdmi/

Theoretically yes. In practice, it depends on the circuitry - from the specific port to the entire chipset.

Somehow I connected the TV to the video card via S-Video. Actually not the first time, the technology has been worked out. When you bring the connector to the PC, a small spark runs between them. There is no image, the computer plows.
Draw your own conclusions.

If "mechanically" means physical damage, then it's easy! He pulled it to the side - a crack went, the thread went somewhere in the area of \u200b\u200bthe bridge - that's all. Regularly this can happen with the same phones. On a computer, it’s more difficult - but you don’t have to be a Hulk either.

A USB device can short out the power pins, which can at least burn out the USB port.
But usually the USB connector is designed in such a way that it is difficult to insert it incorrectly.

A shorted USB usually shuts down the computer, I've tested it myself.
Early USBs couldn't handle reverse polarity, this was a real problem when pigtail wiring wasn't standardized. I didn’t encounter it, I got my first computer with USB 2.0 in 2008 and then everything seemed to be not so gloomy.
Headphones short circuit is not harmful.
UPD. The USB standard is such that the device MUST withstand polarity reversal, but "it was smooth on paper" ...
UPD2. The insertion of headphones in computers is determined by the physical presence of the pin, in phones - as it should.

Wait, I don't understand... it's the panel to the motherboard when you connect it. If so, then nothing will happen. It just won't work. But on condition that a component that has current power is not connected to the panel. If there is a current and it is not connected correctly, then there will be a short circuit and the motherboard cover.
