I'm looking for a powered hub with no "tail" -- just a port for connecting a USB-C cable to my iPad Pro. Everything seems to have a little stubby tail on it, which won't work for my application -- I've got the iPad up on a mic stand and am connecting it to audio gear. I'm leery of extension cords for USB, but I guess that's another option... I also need at least 3 USB-a plugs, as well as power passthrough (or plain powered). I can't have any audio interface or headphone jack, as I'm plugging into a separate audio interface. TIA.
