Apologies if this is posted in the wrong sub - just not sure where it should go. I picked up an off-brand Pandora's Box arcade stick. There's two USB ports at the back that accept usb controllers that show up when using the built in emulator (FOR 3P & 4P games) but I've been unable to get the device to show up as a controller on any other device. I've tried pc, nvidia shield and a modded ps3. Tried different cables no joy. Any idea where to start? Thanks
