We plan to use new digital voice recorders. Products are available from Olympus, Sony, and others. All of these digital voice recorders offer file-based audio storage. We would like to take advantage of this feature and move the files to our computers. It is not clear whether there is a difference in the product features described as "USB connection" and "USB direct connection." Is this difference in USB connectivity a concern for file transfer to CentOS computers? Thanks in advance for any information.
