Description

The dmi_hpe_usb_device_t structure holds the decoded HP/HPE USB device correlation record, which describes a USB device the firmware has found at boot on a USB port, and the UEFI boot entries naming it. Devices plugged in later are not described.

The structure is returned by dmi_entity_info for the structures decoded by dmi_hpe_usb_device_spec, of type DMI_TYPE(hpe_usb_device), declared in <opendmi/module/hpe.h>, once the HPE extension module (dmi_hpe_module) is enabled, which it is for HP and HPE servers with UEFI firmware from Gen9 onwards. It lives as long as the context it has been decoded in.

Fields

port_handle: Handle of the USB port connector correlation record (type 238).
vendor_id: USB vendor ID of the device.
is_sd_card_present: Whether an embedded SD card is present.
usb_class: USB class code of the device.
usb_subclass: USB subclass code of the device, named by dmi_hpe_usb_storage_subclass for the devices of the mass storage class (0x08).
usb_protocol: USB protocol code of the device, named by dmi_hpe_usb_storage_proto for the devices of the mass storage class (0x08), and by dmi_hpe_usb_hub_proto for the hubs (class 0x09).
product_id: USB product ID of the device.
raw_capacity: Capacity of the device in megabytes, zero if not applicable.
capacity: Capacity of the device in bytes, zero if not applicable.
uefi_device_path: UEFI device path.
uefi_device_name: UEFI device structured name.
device_name: Device name.
location: Location of the device.

Standards

Not part of the SMBIOS specification. Defined by HP and HPE for their servers; the layout is the one dmidecode documents.
