Pc does not recognize moto x4 in fastboot mode

Hello everyone, before I decide to create a topic in the community I want to report that I tried "everything" to solve my problem, I searched the internet for solutions and nothing, I believe that I will have a light here.
My moto x4 device with android 9 is recognized by the pc when it is on, but in fastboot mode the pc is unable to recognize it, I have already downloaded all the necessary drivers, tested on two different PCs, used all the USB ports, installed the ADB and FASTBOOT, gave the command via cmd to restart in the fastboot, but it simply seems that nothing I do is able to fix this, in the device manager the following information appears:
unknown usb device (device descriptor request failed)

I've tried to update and uninstall, but nothing happened too, remembering that when the device is on it works perfectly on USB.

My operating system is windows 10.
