HID Interface

The UA variant of the device supports a HID interface. The HID interface adds support for USB standard input and output reports for a telephony device. The GPIO button and LEDs on the XK-VOICE-SQ66 development kit are mapped to buttons and LEDs in the HID input and output reports. The HID Interface design section of the Programming Guide describes the HID descriptors and the mapping between HID buttons/LEDs and the XK-VOICE-SQ66 development kit buttons/LEDs in more detail.
