https://community.sony.se/t5/portable-audio/sony-nwz-e585/m-p/2054360#M2663 <P>I bought mine yesterday and am having the same issue. When I plug it into the computer, Hitachi&nbsp;or Denon hifi&nbsp;mp3 docking ports, the Walkman&nbsp;displays the same message 'Connected USB. The player cannot be operated'. I haven't put any music on it yet, it won't let me. I did expect to be able to play the default, installed albums but the thing won't let me. Good luck. It feels like a nice piece of kit but I'll be returning it if I can't use it.&nbsp;</P> Wed, 11 Nov 2015 11:13:34 GMT Mowzark 2015-11-11T11:13:34Z https://community.sony.se/t5/portable-audio/sony-nwz-e585/m-p/2005116#M2585 <P>I was transferring files from my library onto my MP3 player ( which is only a couple of weeks old) when it suddenly became blocked on the screen saying 'Connected USB (MTP) The player cannot be operated'. I unplugged the USB cable and is says the same message and all the function buttons won't work! Has anyone any ideas how to unblock the Mp3 player?</P> Thu, 27 Aug 2015 14:23:14 GMT https://community.sony.se/t5/portable-audio/sony-nwz-e585/m-p/2005116#M2585 CowlingND 2015-08-27T14:23:14Z https://community.sony.se/t5/portable-audio/sony-nwz-e585/m-p/2054360#M2663 <P>I bought mine yesterday and am having the same issue.
