^ that thread has the information. I don't have oscilliscope to examine the pulse length unfortunately. I don't know what else would be causing interrupts to be lost otherwise.

Because SOF intterupt generates every 1m second(= 1000ns). That is, interrupt signal is not stay LOW LEVEL. Is it really?
