Billy - I get two error messages:
* The windows error says " One of the USB devices attached to this computer has malfunctioned and windows does not recognize it"
* The AHP software error I get when I start the program says "The Active Home Pro USB interface isn't connected to your computer" (it is, of course, connected)
Normally, I will connect the AHP USB interface to program it and then disconnect it. When I re-connect it for more programming, I connect it to the same USB port.
So when I get these errors, I do the standard "Remove batteries, un plug...." and then re-connect the interface. I can't think of anything I'm doing to cause these errors - except for disconnecting the unit from my computer, which, from what I've read, shouldn't be a problem.
Maybe I should just keep it connected to my computer?
