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.
