USB support and functionality

USB support

HP provides both standard USB support and legacy USB 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 51)."
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.
