Xbox 360 controller doesn't work on my android TV box but will work on my android tablet via OTG cable

Want to play my collection of 10p games i bought from the playstore on my android TV box. My xbox 360 wired controller doesn't seem to do anything apart from the green light just flashes. I've seen on Youtube that the controller does work on an android TV box but mine doesn't. Any smart people out there suffered from this or know of a solution? I bought one of those cheap look alike usb super Nintendo controllers from China and they work no problem but would rather use my xbox controller.
