Just downloaded the new version and it works with my eDGe! First connection Calibre crashed but I restarted it and it seems to be ok.

It looks like it is putting the new files on the internal storage in download\news but I will do further testing.
Just excited this is now working. Calibre cannot see the SD Card at the moment and I think this is an issue with the eDGe. When the eDGe is connected to my Windows 7 PC you only see the internal storage in My Computer.
If you add something to your library but delete the file from the Calibre software on your desktop it does not remove it from the eDGe's library. I think it will only remove the copy of the file in the download folder.
So just a first post I encourage folks to give this a try and provide feedback. I have been sending the developer debug information to get this working. This is still in beta and I imagine things will get changed in future releases.
I added an expanded article on this on my web site:
