OK, I am looking for a way to keep Calibre from scanning devices every time they are plugged in. Calibre has no need to know what books are on the device if we are not going to be removing anything from it. There is even less reason for it to be reading the metadata from every book, especially when you have deselected metadata from being read in the options. The speed at which Calibre does this is also horrendous.

What makes this even worse is you can not stop Calibre from scanning a device that is plugged in, nor can you stop the job once it has started. I can not begin to even describe how poor this behavior is, and there are more than a few reasons why this is a very dumb thing to do.

A couple of examples quickly would be that when android devices 'sleep' they can disconnect from the computer crashing calibre and forcing you to start over from scratch. If your just looking to transfer a couple books over it can be a very long wait if you have many books on your device.

Making it faster to just open the folders for each individual book you want to transfer and manually coping them over. For instance it takes over 4 and a half minutes for calibre to scan my phone alone, and my tablet has even more books on it, and less than 10 seconds to copy a folder over via windows explorer.

If Calibre does 'want' to know what is on the device then it should be keeping a record of what was on the device the last time it was accessed so it can cut down on what it needs to scan, or ask to update its catalog.
