This is used to filter [[#UsbHsInterface]], the query commands will only return the interface when these checks pass. This is also used for events with [[#CreateInterfaceAvailableEvent]]. When a bit in Flags is set, the associated descriptor field and the field in this struct are compared, on mismatch the interface will be filtered out. Passing Flags=0 is equivalent to disabling filtering since none of these checks will run. | This is used to filter [[#UsbHsInterface]], the query commands will only return the interface when these checks pass.
