I'm going to assume you have mass storage mode/Media Transfer Protocol (MTP) enabled in memory options. If that is the case, change to off or diasable or whatever. Then try again and see what happens.
If the error goes away and Desktop Manager connects and you are able to sync contacts, calendar, etc. and do backups, that will be a partial solution.
At any rate, do the above and let's see what happens.
