I have Lenovo Z50 with Windows 8.1 it has 2 usb 2.0 and 1 usb 3.0 ports. All of the usb ports keeps disconnecting from android devices, I have tried different cables with 4 different android devices on all of three ports and every time it kept disconnecting and reconnecting. Other usb devices such as thumb drives or wireless mouse usb connector work as intended. It seems problem is isolated with android devices only. How can I solve it?
Note: When I bought my computer was working properly, I am not sure what changed but problem started a few months after I bought the computer.
