One interesting point about hubs, however, is that many main boards (and Notebooks) contain a USB hub. This - and the fact that hubs are not terribly mobile usb devices in general - make this whole category relatively unexciting for BadUSB.

The majority of controllers found in web searches appear not to feature firmware upgradable microcontrollers. They are required by specification to have EP0/ctrl and EP1/int. Hubs are in principle a viable target for BadUSB style attacks.
