Depends on what you mean by a re-install... Asking Windows to check the driver and install the correct/latest one did not help. Deleting the driver totally and then removing/reconnecting the USB end of the interface cable got it to find the correct driver. So at least I can talk to my device programmers, etc, again. Quite why the software decided to replace that driver for me without telling me is a mystery. Needless to say I am not going to run it again. > > Long ago, I learned, the hard way, that I should always make a complete > backup, or at least a restore point, before installing anything new, or > making any change. > > I wish that I would remember to apply that lesson more consistently.
