The widely used open source firmware candleLight has optional support for reading/writing of an user defined value into the device's flash. This is indicated by the GS_CAN_FEATURE_USER_ID feature. The corresponding request are GS_USB_BREQ_GET_USER_ID and GS_USB_BREQ_SET_USER_ID. This patch documents these values.
