Anyone know which USB device it's expecting?
On the hunt for: Dinoking, Mushiking, Love & Berry, Egret 29, Grand Am Q25, Capcom New Concept 2, and Naomi guncabs.
Most times that I see maimai for sale it is accompanied by a usb dongle separate from the keychip that is connected with an adapter cable and ziptied to the ringedge. Not sure if that has anything to do with the issue you are having.
