HP ProLiant DL580 Generation 3 Server Maintenance and Service Guide
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
