i have a 4-port usb hub and i connected it to my android usb otg port
it works but for some reason when i connect multiple joysticks all of them are recognized as "pad1" so i cant map them for different players

if i use usb/bt joystick center it does recognize them as different devices but i cant get any emulator or app to make them recognize them as different joysticks

OTG isn't a PC USB implementation - it only recognizes one device of a kind. (There's a way to get it to take both a keyboard and a mouse, for example, but not 2 mice - which just "works" in a PC.)

IOW, you most likely can't (unless you know how to rewrite the ROM).
