On the back of the Titan towards the top there should be a removable cover. If you remove the screws and then remove the cover you should see another USB slot and a CF card adapter with a Cf card. Try using the USB slot here to see what happens. I am guessing that it may be more of an issue with the CF card or the adapter that has gone bad if you are still unable to use the USB. You can try to replace the CF card with a new one to see if that resolves the syncing problems.
