`UsbdVersionInformation`

A USBD_VERSION_INFORMATION structure that provides version information for the host controller driver (HCD) and the USB specification version that the device supports.

`HcdPortCapabilities`

This member is reserved for system use.

`Traits`

A set of bit flags that identify device traits. The flags are defined by the WDF_USB_DEVICE_TRAITS enumeration.
