Takes an input u32 and a type-0x6 output buffer, returns an [[#IClientIfSession]]. On [3.0.0+] this takes an additional type-0x6 output buffer, before the original buffer. On [3.0.0+] the first buffer is 0x70-bytes, while the second one is 0x1B8. The user-process has the second buffer address immediately after the first one, which allows getting a complete [[#UsbHsInterface]].

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.

[7.0.0+]: The filter struct has to be unique, it can't match any existing filter structs used by [[#CreateInterfaceAvailableEvent]] (including other processes). Hence, Flags has to be non-zero. When initialized with usb:hs:a and VID and/or PID filtering is enabled, the VID/PID will be checked [[#HidGamepad]], with an error being throw if a matching device is found with quirk "ApplicationBlacklist" ([[#usb:qdb|usb:qdb]] cmd1 is used internally for this with bcdDevice=0).
