My phone can't recognize xbox 360 wired controller via otg. But it can work with mouse, keyboard, usb data storage e.t.c.
I've seen several issues on forums, so i came to a conclusion  that it's driver problem. Version of the OS - 7.1.7.0ru(unable to update without breaking warranty ).
That's why i have 3 questions:
1) Is it really bcs of the absent driver?
2) Can it be fixed without root and bootloader unlocking ?
3) Does this problem appear on different versions of Flyme?
