I've tried a Zen Vision: M AND a Zen V. got the 'INF' error message both times. Could it possibly be that the MTP requires USB 2.0 to work? Neither player charged, even though when i plugged it in the computer didn’t recognize it. Someone said USB 1.1 will not work for MTP transfers? So I’m going tomorrow to upgrade my USB's to 2.0. Hopefully that will fix it.
