computer ancillaries.
Some USB devices require driver installations and/or switch settings before or after they are connected
to ShieldPRO.

After disconnecting a USB device from ShieldPRO, wait for three seconds or longer before the device is
connected again.
If the connector of a USB device is connected to ShieldPRO quickly or at an angle, ShieldPRO may not
be able to read signals properly to recognise it as an unknown device. If so, remove the connector from
the USB connector and reconnect it again.
