The set is obtained by OR-ing. Say Y here only if you are absolutely sure that you don't want to use the generic HID driver for your USB keyboard and prefer to use the keyboard in its limited Boot Protocol mode instead. Because it was understood that not all hosts would be capable of parsing HID descriptors, HID also defines "boot protocol". I'm going through the HID documentation. hid(7d) handles all communication with the USB host controller via usba(7d) (analagous to usb-core on Linux) hid(7d) is a STREAMS driver – Individual HID devices can use a STREAMS module pushed onto the driver to handle the device – There is no documentation for writing such a module The hidparser module handles HID descriptors. It does this by providing full report descriptor and report parsing capability. [Endpoint Descriptors] Like the configuration descriptor, the endpoint descriptors were changed in v2.
