Is there short circuit protection in USB?

Question

Iron

The story is like this. The mouse began to glitch. Left-clicking did not always work, and sometimes instead of a left-click, a context menu popped up, as if I was right-clicking. I took out an old mouse, disassembled it, cleaned it of dust, replaced the rubber wheel with another of the same mouse. Then I rubbed it with 70% alcohol to remove the dirt. And immediately turned it on. She worked and soon went out. There was a smell of burnt electronics. I looked, on the electronic mechanism that reads the rotation of the wheel, the alcohol has not dried. Actually, the main question. Could something have burned out because of this? If something shorted out in the mouse, how could it affect the USB of the computer? Is there any protection against this? Although there is still a version that the problem, on the contrary, is in the voltage on the USB, which spoils the mice.

Answer 1

there is protection

Answer 2

Of course, it is, since the supply current via USB is fundamentally limited: for 2.0 it is 0.5 amperes, for 3.0 more - 0.9 amperes, and for 3.1 it is even more significant (I don’t remember the exact number). This protection is implemented in the form of the so-called. "self-healing" fuses. In old motherboards, they looked something like this:
and like this:
and in modern ones - like this:
