Hi group,

Does someone performs USB Mouse CETK test? One of the test item is ask
you to press left/right mouse and drag. On screen there will be lines
drawn following your dragging trace.

But I find that their will be blank segment if I draw a very long
curve, also if I drag / release / drag very quickly, there will also
be lines that are blank. However the cursor track line are correct.

Is this test result acceptable?
