USB Mass Storage working only with the prebuilt lib, and not from USBX Source

Hello,

I am testing the USBX_Mass_Storage_Host for S7G2 DK board with SSP 1.5.3. The example is working as expected. However, if I enable the USBX Source in the configuration, to not use the libux.a prebuilt library, but to compile the source files, the example is no longer working (not even the USB detection).

In my code, I need to use the USBX Source, as I have the ThreadX Source already (mandatory for custom configuration), and by removing the USBX Source I get a configuration warning that I mix both prebuilt library and source files.

So, could you please clarify why the USBX_Mass_Storage_Host example is not working when building the USBX from source files (with the default configuration).

Thank you,

Valentin
