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.
External USB functionality
HP provides external USB support to enable local connection of USB devices for server blade
administration, configuration, and diagnostic procedures. For more information, see "Using the HP c-
Class Blade SUV Cable (on page 45)."
For additional security, external USB functionality can be disabled through RBSU. Disabling external USB
support in RBSU disables the USB connectors on the HP c-Class Blade SUV Cable.
Internal SD support
An internal SD connector is available for use with embedded Hypervisors. This solution provides for use of
a permanently installed SD card in the internal connector, decreasing the possibility of tampering or loss.
