Problem with etecher recognising mounted sd card under centos 7

Etecher installed fine under Centos 7 even shows up as a utility under the menu in the GUI
I can launch the app and select a image but it cannot find my sd card that can be mounted and shows up on the desktop … i even tried reformatting the FAT FS that was on the sd card so it was a Ext4 FS and remounted it with no joy… also shows up on desktop but unrecognised by etecher…

any thoughts or suggestions

Thanks in advance
