Verified the Serial communication from Native port with the changes to USBCore posted here by dreschel :
- my 4096 byte long send package started working OK after making the changes proposed by dreschel !
- earlier only 512 bytes came through and of course thought I had problem in my own code , but it was actually in USBcore
with this experience I recommend also making changes to next Arduino Due program release and of course the earlier change concerning
Native port BsOD,
BR and thanks to dreschel,
