iPod Classic mounts then immediately dismounts
iPod Classic works perfectly, but will not stay mounted in Ventura(13.5.2) to be synched. Icon appears on desktop then immediately disappears. iPod displays "Connected, eject before..." then quickly jumps to "OK to disconnect". iPod never shows up in Music, Finder or Disk Utility. Shows up in System Report as a USB device, but not as a storage device. Have tried the Menu+Center button reset - no change.
I see similar threads, but no recommendations that I haven't tried.
Thanks!
