Admittedly, I cut apart a USB cable and am using socketed pin headers |
40 |
to attach it to the development board (I'd like to keep it looking |
41 |
nice). However, this same board properly identifies as a USB CDC |
42 |
device to Windows. |

There may be an issue with the kernel driver, Meino. I'm going to see |
45 |
how I should follow up on this. Can you test your ATtiny85 with |
46 |
Windows? |
