The endpoint buffers are physically at 0x1b40-1FFF for chips with 8k RAM.
Accessing these buffers at the mapped addrerss don't mean that the 
physical address
is also there. The idea is that if newer chips have more then 8k ram 
accessing the buffers at
0x7b40  then the software runs without modification.

So make shure and check with the map file that no code or data is linked 
into 0x1b40-1fff region.
