This is an improvement for the special
mode present in the samsung ypr0 target.
Apart adding new useful functionalities, it
fixes a random disconnection bug, solved by debouncing
and fully support to YP-R1 target.
This opens also the possibility to interface
this operating mode to rockbox USB functionality.
