If that's the case, you have some kind of Windows problem.
Windows does not lose the interface usually. Neither does AHP.
Can you tell us exactly what's happening and when.
thanks for all the attention. i am using 2 timers on dusk and dawn setting and 2 macros for lighting.( i am not using flags...1,15,16) i have no problem linking to the cm15a with the usb port and ahp sofware.
when my timers fail to come on i use the computer to turn on the lights(so my conditional macros will know they are on), but i get the "device not reconized"
I never get this unless the unit fails. a simple unplug from power and plug back in corrects this and corrects the failing timers. but i should not need to remove the power every day for this to work.
so the only time i get "device not reconized" is when the device has already failed.
as far as a window problem....the problem is in the cm15......it locks up and will not let the usb interface hook up.
