My issue is that I have a Galaxy S6 Edge (unrooted, 5.1.1), a UGREEN USB OTG cable, and a Microsoft Wired Xbox 360 Controller, and I can't seem to get it to detect my controller at all. I know my phone supports OTG, and that this OTG cable works because I've plugged a mouse into it and it was just plug-and-play, I could do whatever I wanted with the mouse with 0 issues. Well when I plug my Xbox 360 controller into it, which is from Microsoft and is for Windows/Xbox 360, the green lights around the dashboard button are blinking as if it's getting power/connected, but I can't do anything with the controller. Does anybody have any idea what could be the issue? I have searched forum after forum with no luck, have downloaded (some I even paid for) every app I could find that's supposed to help, and I'm just about to the point of throwing the controller in the trash and giving up on using an external controller.
