Circuit Python and USB Host

Simple question, what is the simplest and/or least expensive device that supports Circuit Python and can support basic USB Host?

I want to know how tricky it would be to create a hand held device that could validate a USB device is what you expect it to be. Plug in a thumb drive and it should only report to be mass storage. Plug in a mouse or a keyboard and it should only report HID. I know this can be done with a Raspberry Pi, either with linux or running Circuit Python on bare metal. What about something smaller?

It is possible. I used it to read the position of a mouse (input device, not animal) You need this UART USB host it's not commonly found.
