HUB_DEVICE_CONFIG_INFO structure
The HUB_DEVICE_CONFIG_INFO structure is used in conjunction with the kernel-mode IOCTL, IOCTL_INTERNAL_USB_GET_DEVICE_CONFIG_INFO to request to report information about a USB device and the hub to which the device is attached.
Syntax
typedef struct _HUB_DEVICE_CONFIG_INFO { ULONG Version; ULONG Length; USB_HUB_CAP_FLAGS HubFlags; USB_ID_STRING HardwareIds; USB_ID_STRING CompatibleIds; USB_ID_STRING DeviceDescription; } HUB_DEVICE_CONFIG_INFO, *PHUB_DEVICE_CONFIG_INFO;
Members
- Version
-
Specifies the version number. Must be set to 1.
- Length
-
Specifies the size of the HUB_DEVICE_CONFIG_INFO structure. Must be set by the caller.
- HubFlags
-
Specifies the hub capabilities in a USB_HUB_CAP_FLAGS structure.
- HardwareIds
-
The PnP hardware ID multi-string for the USB device in a USB_ID_STRING structure.
- CompatibleIds
-
PnP compatible ID multi-string for the USB device in a USB_ID_STRING structure.
- DeviceDescription
-
Description of the device in a USB_ID_STRING structure. This may be set to NULL.
Remarks
The Buffer member of the USB_ID_STRING structure points to a string that contains HardwareIds, CompatibleIds, and DeviceDescription values. The caller is responsible for releasing this string buffer, which is allocated by the hub driver.
