@buzzyc some hubs work right and some dont. I did a gameboy zero with an all in one-ish board and the usb hub built on the board reads the built in on board controller fine and the usb reads my wireless mini usb/trackball mouse. But it wont recognize my wireless n adapter and my full size keyboard crashes it. But in my arcade block mini genesis usb hub and the rockband hub i can run everything just fine. Mostly. On my rockband hubs if i have to set up wifi i need to remove everything but the wifi and the keyboard otherwise it takes like thirty tries to get the pi zero to accept the wifi key. Havent tested that on my genesis usb hub
