Hi There
I've been happily hacking away with my new Pro Micro (Leonardo).
Suddenly, this evening, I am unable to upload sketches via my PC. I tried the same USB on my laptop and it does work.
I get the following output from the web editor when trying on my PC.
I have done some reading. And it looks to be an issue with the com ports swapping when the bootloader is initiated? I can see that when I rest the Arduino it swaps from COM5 to COM6 then back to COM5. It does the same when I am uploading the sketch.
Any help would be greatly appreciated.
Many thanks.
