USB 2.0 Connectors

The Compaq Evo D310 Micro Desktop features 6 USB 2.0 connectors (4 rear and 2 front).

USB 2.0 extends the speed of the connection from 12 Mbps on USB 1.1 to 480 Mbps on USB 2.0, providing an attachment point for next-generation peripherals for use with higher performance PCs and user applications. USB 2.0 is both forwards and backwards compatible with USB 1.1 and uses the same cables and connectors as USB 1.1. Externally USB 2.0 system looks no different from a USB 1.1 system.

USB 1.1's data rate of 12 Mbps is sufficient for many PC peripherals. These peripherals will continue to operate with no change in USB 2.0 systems. The higher bandwidth of USB 2.0 permits the use of PC peripherals with wider functionality. The higher bandwidth supports the most demanding PC user applications, where multiple high-speed peripherals are running simultaneously. When using a USB hub it is important to make sure that you use a USB 2.0 compliant hub.

USB 2.0 drivers are not preloaded on the software image, they can be downloaded from HP’s Support web site at: www.hp.com/go/support.
