@jahughes41
This is an issue with calibre, not Android.

A moderator has now moved this thread to the appropriate forum, for better visibility. Hopefully you will get an answer now.

Run

calibre-debug -d

in a terminal and post the output

Also most likely this is a permissions issue, you can check that by running calibre as root and seeing if it connects to your device.
