Mach1GTO, CP3 controller.  I cannot connect to my mount.  I've uninstalled-reinstalled the latest V2 driver and FTDI driver.  I installed the latest version of APCC.  I've unplugged-replugged all cables, several times.  This gear has always been picky about turning on the mount power before turning on the computer, so I've been diligent about shutting everything down, letting it sit a bit, then restarting.the mount first, then the computer.  I went through something like this during the winter, but plugging the FTDI adapter into a different USB port got it working that time.  No joy this time.  Device Manager says the FTDI driver is working correctly.  Should I just assume that any or all pieces, from the FTDI controller to the CP3 driver, are defective and need to be replaced?  I'm at a loss to explain this or to come up with a solution.  I'm looking for suggestions about something I've overlooked.
