I’ve been programming my Arduino using a Macintosh. I am familiar with the ‘Port Problem’ which I have encountered previously with stand alone Arduino boards. The Port Problem is when an Arduino is connected through a USB connector, and the connection port fails to show up in the Port… menu of the Arduino IDE (I use version1.6.0).
Usually quitting the IDE, unplugging the Arduino board (or bit), then restarting and replugging everything fixes the problem and the port is restored.
Recently I was reprogramming my Arduino bit for the World Time project, and encountered the Port Problem. My fix did not work. I tried everything from this thread, I shut down and restarted everything, and even shorted the RESET to the GND lines from the ISP connection momentarily to try to reset the Arduino. None of it worked, so in a panic, I burned the bootloader using a Pocket Programmer, and uploaded my sketch to the ICSP pins using the programmer. This worked, but the DX and RX lights are now always on. And the USB ports remain invisible - I can only program this bit using the programmer now.
I bought another Arduino bit, and it works perfectly, so I know the computer’s USB ports and software are fine. (Note, I have made the USB power modification on both my fully-functional and broken Arduinos. This problem is probably unrelated, as it appeared long after making the modification. I feel it broke when I used the programmer on it.)
Is there anything I can do to restore the malfunctioning Arduino bit? Thank you for any ideas and assistance!
