can you connect a wired controller through a pc to an android without plugging it into the tablet itself i say this because i dont have an usb otg cable or whatever its called and i dont want to go out and buy one
some applications are made to interconnect an android device and a personal computer for casting or to make the android device do the job of a mouse for example. but your way is impossible because there hasn't been any software which allows a device to connect to android through PC and the fact is there is no need for it. or else nobody has developed a software for it. 
better u buy it from amazon. its cheap nowadays
