Good day. A want to ask two questions. When I connect my Oppo Find 5 to PC in only charging mode, appears two disk letters E: and G: First is CD Drive named "Linux File-CD Gadget USB Device", and second is Removable Device with the same name "Linux File-CD Gadget USB Device" in device properties. Both disk drives are empty. Also appears standard Android Composite ADB interface. When I switched to Storage Device mode, in letter G: appears all files from internal phone memory, but E: stay empty. I want to ask. First. Is it normal, or I have some bugs or wrong settings in internal USB controller in phone? And second. If it normal, how can I disable this empty CD Drive?
