Not sure when [this](https://docs.espressif.com/projects/esp-idf/en/stable/esp32s3/api-reference/peripherals/usb_host/usb_host_notes_dwc_otg.html) page was published, but it looks like we may have a linux driver for the USB controller after all. I'll try to configure it.

USB host has been added to the Box3 configuration with support for HID and mass storage devices.

Thanks for the ping, will do it shortly.
