Why does the computer shut down when a USB flash drive is connected?

Question

USB

There is a 3.x 8GB flash drive with a second micro-USB connector and a metal case. When trying to connect a flash drive to a computer (2.0 ports) through the front panel, it is very rarely detected by the system.
When you try to connect to the connector on the motherboard, the computer is cut down and the power supply goes into protection for a few seconds (as I understand it, because the power button does not respond and the mouse backlight goes out, working from the duty room)
Other devices (2.0 flash drive / keyboard mouse / dongle from the gamepad) into this same port connect ok

Answer 1

Are there any other flash drives in a metal case? Did you connect it through a hub / monitor / extension cord? If the PSU goes into protection, then the flash drive closes the power to the case

Answer 2

Statics.
