USB support and functionality
USB support
HP provides both standard USB 2.0 support and legacy USB 2.0 support. Standard support is provided by
the OS through the appropriate USB device drivers. Before the OS loads, HP provides support for USB
devices through legacy USB support, which is enabled by default in the system ROM.
Legacy USB support provides USB functionality in environments where USB support is not available normally.
Specifically, HP provides legacy USB functionality for the following:
• POST
• RBSU
• Diagnostics
• DOS
• Operating environments which do not provide native USB support
Internal USB functionality
An internal USB connector is available for use with security key devices and USB drive keys. This solution
provides for use of a permanent USB key installed in the internal connector, avoiding issues of clearance on
the front of the rack and physical access to secure data.
