USB support

Hewlett Packard Enterprise servers support both USB 2.0 ports and USB 3.0 ports. Both port types support installing all types of USB devices (USB 1.0, USB 2.0, and USB 3.0), but might run at lower speeds in specific situations:

  • USB 3.0 capable devices operate at USB 2.0 speeds when installed in a USB 2.0 port.

  • In UEFI boot mode, Hewlett Packard Enterprise provides legacy USB support in the preboot environment before the operating system loads for USB 1.0, USB 2.0, and USB 3.0 speeds.

  • In legacy boot mode, Hewlett Packard Enterprise provides legacy USB support in the preboot environment before the operating system loads for USB 1.0 and USB 2.0 speeds. USB 3.0 ports can be used with all devices in legacy boot mode but are not available at USB 3.0 speeds in the preboot environment. Standard USB support (USB support from within the operating system) is provided by the OS through the appropriate USB device drivers. Support for USB 3.0 varies by operating system.

The pre-OS behavior of the USB ports is configurable in the Aptio Setup Utility.
