Hi Henk,
Thank you for your suggestions. I confirm that everything is working fine. For anyone with similar requirements here is what is required to get the lib_usb and xscope debugging working on the XEF232-1024. I am using the USB CDC as a virtual com port mostly connected to Windows 10 without any problems.

The XN file created by the tools has to be modified with changing references to the usb_tile from an array "usb_tile[2]" to 2 different names. I have used usb_tile and usb2_tile.
This way when the 'usb_tile" is passed in the lib_usb it will not throw an error for incorrect type.
In the XN file posted bellow a link has also been added for XSCOPE.

The following xcc flags have to included in the makefile for the usb to work:
-DXUD_SERIES_SUPPORT=XUD_X200_SERIES -DUSB_TILE=tile[1]

For the XSCOPE to work for debugging:
1)I have added the -fxscope flag the makefile xcc flags
2)Added a config.xscope file with this declaration: <xSCOPEconfig ioMode="basic" enabled="true"/>
3)Set the target IO options to Xscope in the Run configurations.
