Hello,

The only functions that are available for the FT4222 are detailed in the following:
https://www.ftdichip.com/Support/Documents/AppNotes/AN_329_User_Guide_for_LibFT4222.pdf (https://www.ftdichip.com/Support/Documents/AppNotes/AN_329_User_Guide_for_LibFT4222.pdf)

Appendix D lists the supported D2XX functions, of which FT_GetQueueStatus or FT_GetStatus is not supported.

I would suggest having a look at the examples available on the following page:
