I've said it before and I say it again under these conditions what you have
described sounds a lot like a
hardware configuration problem.
ONCE ALL THE HARDWARE BUGS ARE FIX THE SOFTWARE MAGICALLY STARTS TO WORK
CORRECTLY.
I've seen this 100's of times hardware guys can't find the problem so the
solution is to blame the software.

if(( byte_to_send & 0x0e) != 0 )
{
byte_to_send |= 0x02;
}
Why would anybody write a piece of code like this in side a packet? I can
think of lots of reasons to write code like this but not to send a packet.
Find this next hardware bug and any further hardware bugs and the software will
start to work correctly.
How do I know this I've seen it 100's of times.
