USB Device

[Rodrigo]

If I connect a new universal serial bus (USB) device to a USB 2.0 hub on a
computer, the computer does not detect the USB device.
Additionally, other USB devices that are already connected to the computer
stop functioning, and I have to restart the computer to detect the USB
devices. If the USB device is already installed on start, I have no problem.
The Legacy USB Support is disabled.
