Compaq Armada V300 Series Reference Manual page 92

Your computer comes equipped with a port that connects
Universal Serial Bus (USB) devices to the computer.
Your computer can support certain USB devices without any
special drivers. These include hubs and keyboards. To connect
USB devices for which the device manufacturer provided no
special drivers, you will need an operating system that has USB
support, such as Windows 95 or Windows 98 preinstalled by
Compaq. Later versions of the Windows operating systems will
add functionality that may allow you to attach any USB device to
your computer (for example, a video camera) and allow many
USB devices to be connected and working simultaneously.
A USB keyboard and mouse, optionally connected through a hub,
offer the same functionality as a standard keyboard and mouse
connected through the keyboard/mouse connector. Future
operating systems will have extended USB capabilities which will
replace the USB capabilities built into the computer.
To connect the computer to a port replicator, refer to the
instructions that came with the docking device.
