Error message by calibre

[alroy]

I have a Aluratek Libre. Everytime I transfer a book from cabre to this device i get the error message "error communicating with device". However, the book does show up on my eReader. Anyone know how to fix this so the error message does not show up?

I transferred about 20 books (pdf, epub, free and purchased books) to my libre pro today and the message didn't occur once. Will have to re-post the message if and when the error message occurs again.
