How to see if the motherboard USB is active

If the USB device is plugged into the computer, when the system is "indifferent" to the device, you may want to check whether the USB port feature in the computer's motherboard has been started, and if the port feature is not enabled, the USB device will not be automatically recognized by the system when it is plugged into the USB port on the motherboard. When you enable the USB port feature in the motherboard, simply turn on the computer's BIOS parameter setting interface to locate the PNP and PCI Setup entry (which is also the "Pnp/pci Configuration" setting), and the "USB function" The parameter is set to "enable" (Some also set "Assign IRQ for USB" to "enable") so that the USB port feature on the motherboard is enabled.

However, if you just want to see if the USB port feature in the motherboard is enabled, you can simply not reboot the computer system and go to the BIOS parameter setup interface, just open the System Device Manager window to see if there is a "universal Serial Bus Controller" option in the device list. Indicates that the USB port feature of the motherboard has been enabled. If you do not find this option, then you enter the system's BIOS setup interface to enable the motherboard's USB port features.
