there is no firmware dload for it. so i doubt its a usb issue due to its firmware... likely faulty component inside printer on board. likely u plugged in and didnt install driver first. and the UAC stopped driver install.
i tried everything but nothing. i also tried to install that printer to another PC but same problem occurred.
i changed usb cable with another cable which was connected to other PC for testing and it worked in that PC. so the cable was problem. thanks above all of you.
