i test this driver between blackfin board and board, and found that also have
this problem. one board can recognize the other board, but verse can't.so i
guess it is maybe hardware problem,one of them is bad.

Disable the push button switch(SW5) pin 1,2, for GPIO PF2 and PF3 multiplexed
with uart1 tx rx.

now, it is ok.
so closed it.
