Upon launching calibre recognition of the device is very erratic, sometimes nothing, sometimes OK.
I don't have a Mac or a Kindle but my guess is if you want it to work consistently with calibre, stop ejecting it. At the very least reconnect it while you are using calibre then eject it when you're done using calibre.
