I have attempted to demonstrate the sample code for "USBXTm Host Class Mass Storage," but I encountered the error "UX_HOST_CLASS_INSTANCE_UNKNOWN."
Yes, I have formatted the 16GB USB stick with FAT32 and a 32KBytes allocation unit size.
Thank you in Advance
Sorry for the late response.
It's always recommended to use the latest SSP version but unfortunately the only migration guidance available is from v.1.x to v.2.x;
So I'd recommend you to…
What version of the SSP do you use? If the example code has been created with the earlier SSP version there might be some issues.
If this response, or one provided by another user, answers your question, please verify the answer. Thank you!

Thank you for your response.
I am indeed using SPP version 2.4.0, and the USB project example version I'm working with is 2.2.0. Given the version disparity, I suspect that could be the root of the "UX_HOST_CLASS_INSTANCE_UNKNOWN" error I encountered.
Is there a recommended way to adapt the example code to work with the newer SSP version, or should I consider downgrading to a compatible version for this project?
Your guidance is greatly appreciated.
So I'd recommend you to try to use the original version of the example which is 2.2.0. If it works fine, I'll send the ticket to our development team. Otherwise we'll keep finding the issue on your side.
No problem at all, and thank you for your response.
I understand that using the latest SSP version is recommended. However, it appears that SSP version 2.2.0 is not available for download from the Renesas website. In this case, could you please provide guidance on where I can obtain SSP version 2.2.0 or if there are any alternative solutions you can suggest for this migration?
Unfortunately, older versions of the SSP are available only upon the request using this form www.renesas.com/.../request-older-version
