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
