I can't quite figure out what it's doing wrong but you have :-

for(i=0;i<BUFFER_SIZE;++i)

>> 11 byte counter

and then later on

if(i==0 && read_data == 0x42) continue

>> here I am looking for i=0 and 42

but by pre incrementing i, it can never equal 0 in the second if statement.
/////
//     good point I will check that
/////

maybe the first statement should be :-
for(i=0;i<BUFFER_SIZE;i++)

>> you are right

Maybe a bit more info on what it's actually doing - as well as what
it's supposed to do may assist?
