Hi. My android is: M7206 (2.3.3) kernel version 18.104.22.168 LIZHAODONG@UBUNTU #87, build # GRI40. My android came with an adaptor with two full size USB ports. When I connect a usb stick the android says that the stick is empty and cannot locate the files on the stick. I want to move my video files from one usb stick to a second usb stick. Thank you for your help!
