I am not the one who created so not able to answer. Perhaps Regis may be able to answer.

But there are many ways you can find out what is in.

Compile a pde with CDC function and look at the output.map file. You will see the symbols from the usb_* obj files stored in libcdc.a included in the hex file. This should give you sufficient ground to compare with those in MLA source code.

You can also use mips-ar to extract the obj files from lib file, then use mips-objdump to look at the symbols in them.

Thanks DJ!
I'll try. I'm new to Pic32 and I'm not so familiar with mips gcc.
By th way I put on my board also a fdti chip to connect to pinguino serial in the case i can't use cdc.
By the way if Regis can help me with sources I'll be very happy.. Big Grin (lol)
Best Regards
Roby
