The "boot interface" seems to imply that firmware is downloaded,

A boot protocol interface is a HID interface with a predefined report (specified in the HID spec), its to make life easy for BIOSes which don't want the overhead of parsing a HID descriptor.

This does not mean that the device has downlaodable firmware.

A device will use the boot protocol interface if it receives a SET_PROTOCOL request which tells it to, otherwise it'll just use the normal report protocol, where it uses a report defined by the report descriptor.

Basically all the documentation you need is in the HID descriptor and in the HID spec. -- Barry Twycross email@hidden --- USB, it's not a Dyslexic BUS.
