Banana Pi - Controller compatibility

This is a 2 part question for Lakka running on my Banana Pi… I’m a n00b to Lakka and I’m sure there’s a thread out there for this but I’ll ask anyways… PART 1: Does anyone know if, or use, this type of controller?
It’s an XB360 style USB PC controller, mainly curious if it’s worth getting

PART 2: I have a PS2 to PS3 USB adapter I bought for my old PlayStation 2 controller and it doesn’t seem to work properly since there is no central button on the controller. I can’t seem to find where the “go” button is mapped to to select the highlighted on-screen menu option (but I did manage to get ‘search’ to display (which I can’t get rid of unless I reboot))

Help please!!

dunno about pt 1 but for pt 2, it should be circle button to accept things if your controller is being mapped properly. If not, you’ll need to use a keyboard to go into settings > input > player 1 binds and then ‘bind all’. If you save that autoconfig, you shouldn’t need to keep doing it in the future.

You’ll also probably want to drop into the hotkey binds menu to assign the menu to something (probably select or R3/L3; you could also use one of our hardcoded menu shortcut combos).
