I have had a particular Arduino Nano working in my PC for about 13 months.
Now it doesn't.
When I connect, or unplug it, I hear the Windows "device connected/disconnected" sound.
However, it does not show up in Device Manager's Com Ports list. (It used to be Com19)
Any ideas how to get it back?

So, I am trying to get an Arduino board to connect to my Windows 7 machine. However, after installing the drivers, I can't see which port it is assigned to. There is no "Ports (COM and LPT)" listed in the device manger, and if I bring up the properties for the device it does give me location...
A vendor told me that supposedly Windows 7 has some emulation options for com ports. Is this true? If so how does it work. I have a handheld scanner that is USB, when I plug it into the computer it is recognized as a keyboard (scanner normally in keyboard wedge mode), but I need to use a com...
