I recently upgraded to EA5 and OS3, I have a USB plugged in to my EA5 with music. I can play my music fine but for some reason I can find the EA5/USB on my network so I can manage my music from other PC's in the house. This was not a problem with HC-800 and OS 2.10. Any thoughts on why EA5 wont show up on network? Is there a way to make is "discoverable"? I have tried from 3 different PC's and a Mac, I have rebooted a few times... thanks for any insight.
