USB support
HP provides both standard USB support and legacy USB support. Standard support is provided by the
operating system through the appropriate USB device drivers. HP provides support for USB devices before
the operating system loads through legacy USB support, which is enabled by default in the system ROM.
HP hardware supports USB version 1.1 or 2.0, depending on the version of the hardware.
Legacy USB support provides USB functionality in environments where USB support is normally not
available. Specifically, HP provides legacy USB functionality for:
• 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 USB drive keys only. The internal connector shares the
same bus with the front external USB connector, and connecting a device to both the front internal and
front external USB connectors is not supported. This solution provides for use of a permanent boot drive
from a USB drive key installed in the front internal connector, avoiding issues of clearance on the front of
the rack and physical access to secure data.
For additional security, you can disable the front USB connectors through RBSU. Disabling external USB
ports in RBSU disables both the front external and front internal USB ports.
