The motivation is that I am doing I2C debugging. I thought the "Unsupported operation" meant there was some kind of transmission error, but in fact it was "No such device": literally there was no response from the addressed device. |

The
errnomessages forEPERMandENODEVwere wrong. In particular the ENODEV message was confusingly wrong.This grows builds slightly due to a new string, and alter the errors we see in some circumstances, but I think it's better to have the correct messages. If the mesages are mentioned in any guides, they'll need to be changed, but I think the mentions may only be in issues. I'll do a learn.adafruit.com site search after this is merged.
