I have a Tab 3. When I connect it to PC via USB, PC does not detect Tab and Tab shows red cross at battery level. Tried changing USB cable. Still no joy. Phone is getting charged when I connect USB to adapter for charging. Also same USB cable is able to connect another Xperia phone to PC. Not using SIM in phone. Not able to detect the problem. Please help.

The tablet you are using requires wall charging and it requires high current input which the USB ports of PC are unable to provide and hence Samsung tablet shows red cross on the battery icon.
