Change the "Could not find device ..." to more meaningful

If a device does not found in the device database it outputs "Could not find device ...", which is a bit misleading because at first I was associated that I have HW problem. I propose to change it something like: "Could not find device in the device database: "

This is just a kind of "note issue to myself". Let me know if you agree and I will fix it with a PR.

@martonmiklos It's sad your pull requests weren't addressed at this abandoned repo; could be a good idea to restore them just to increase the visibility of your forked repo. Thank you for the improvements!

@mikebdp2 Yeah I did some cleanup on my github and other stuff to get a clear view on my TODO lists. Leaving PRs open makes sense due to the visibility terms, so I have reopened them.
