I have Samsung Galaxy Tab A 10.1 I cannot transfer files to Windows 10 PC. keep getting error message" Device not recognized" I have checked drivers for updates and everything seems to be ok. When i connect my camera there is no problem. Any help please in simple terms would be appreciated. Edit, I have recently tried transfer with a Tab 2 GT-P3110 and my pc immediately set it up. So any further thoughts would be appreciated.
