I have been using an unpowered USB drive as “MyMusic” connected directly to the Primo. It has worked ok (until now) with the one problem being that I periodically need to force an update of the music database (even though drive has been connected throughout) in order to be able to play anything.
I just returned from vacation, updated to the latest Volumio release (3.251) and figured I would just need to do the Update or Rescan trick to get the music visible to Volumio. Unfortunately, that did not work. I removed the USB drive and connected to my MacBook and the data seems fine. When I connect it back to the Primo, the Primo does not seem to recognize it.
Any ideas?
