Hi Jack,
To my knowledge, the code hasn't been touched at all since 2013 other than being moved from edk2 to edk2-platforms. The move from edk2 to edk2-platforms did happen in 2019, so perhaps something broke during that move but it seems unlikely. The only other explanation I can think of for it working with code from circa 2018 is that something in UsbBusDxe changed that broke FtdiUsbSerialDxe.
Thanks,
Nate

Hi Nate,
The same FTDI device works with the source from around 05/23/2018, unsure of which chip is in there.
Thanks,
Jack

Hi Jack,
I believe that driver has only been tested with the FT232AM, which has not been manufactured for several years now. Ashley (cc'd) implemented it as an intern project in 2013: https://github.com/tianocore/edk2/commit/3f1484f
There probably needs to be some work done to get it running with newer FTDI chips like the FT232RL.
Thanks,
Nate

Hi,
Are there any known bugs with [edk2-stable202002] when using the FtdiUsbSerialDxe driver? I am seeing errors during initialization when TerminalDriverBindingStart() tries to reset the FTDI device and gets EFI_DEVICE_ERROR.
Thanks,
Jack
