USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS union (usbioctl.h)

  • Article

The USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS union is used to indicate the speed at which a USB 3.0 device is currently operating and whether it can operate at higher speed, when attached to a particular port.

Device speed information is obtained in the USB_NODE_CONNECTION_INFORMATION_EX_V2 structure by the IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX_V2 I/O control request.

Or: the speed in which a device attached to a port is currently operating and at what speeds it is capable of operating.

Syntax

typedef union _USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS {
  ULONG  ul;
  struct {
    ULONG DeviceIsOperatingAtSuperSpeedOrHigher : 1;
    ULONG DeviceIsSuperSpeedCapableOrHigher : 1;
    ULONG DeviceIsOperatingAtSuperSpeedPlusOrHigher : 1;
    ULONG DeviceIsSuperSpeedPlusCapableOrHigher : 1;
    ULONG ReservedMBZ : 28;
  };
} USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS, *PUSB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS;

Members

ul
