--- Comment #4 from Alex Deucher <alexdeucher at gmail.com> ---
I suspect it may have something to do with the pulse timing from the monitor. 
Long pulses are for connect/disconnect events and short pulses are a feedback
mechanism for the monitor to the driver.  I suspect the monitor is sending a
short pulse that the driver is interpreting as a long pulse.
