USB_NODE_CONNECTION_INFORMATION_EX_V2_FLAGS union (usbioctl.h)
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.

Members
ul
