USB Drive, TV Camera Ports work well?
I've connected Samsung VG-STC4000 in USB Port 1 and 8GB Sandisk USB 2.0 Pendrive in USB Port 2, Western Digital 1TB USB 3.0 portable harddisk on USB Port 3. The USB Port 3 (USB 3.0) works very well without any issue. But other 2 ports is not working properly. Sometimes camera won't detect motion control/gestures, also 8GB pen drive(or any pen drive) won't get detected by the TV. However If I disconnect and re-connect, it works fine. Also If I restart the TV, it works fine. Do I need to contact customer support? Or any other fixes?
