Rio 500 killed by a Firmware upgrade under iTunes for OS X


I just upgraded my Rio500 Firmware with iTunes to 2.12, after a successful upgrade from iTunes point of view, my Rio500 doesn't mount anymore on the iTunes source manager. Before, my Rio was almost working, but now he is completly dead! Thank's to Apple. PLEASE DON'T UPGRADE YOUR RIO 500 WITH iTUNES UNDER OS X! YOU WILL KILL YOUR DEVICE!
