hog-lib: Make use of UHID_CREATE2 This convert the use of UHID_CREATE to UHID_CREATE2 which gives back the information of reports being numbered or not thus avoiding the need to parse the report map in order to check if there are a report number on them since UHID_START gives that information: UHID_START: This is sent when the HID device is started. Consider this as an answer to UHID_CREATE2. This is always the first event that is sent. Note that this event might not be available immediately after write(UHID_CREATE2) returns. Device drivers might require delayed setups. This event contains a payload of type uhid_start_req. The "dev_flags" field describes special behaviors of a device. The following flags are defined: - UHID_DEV_NUMBERED_FEATURE_REPORTS - UHID_DEV_NUMBERED_OUTPUT_REPORTS - UHID_DEV_NUMBERED_INPUT_REPORTS Each of these flags defines whether a given report-type uses numbered reports. If numbered reports are used for a type, all messages from the kernel already have the report-number as prefix. Otherwise, no prefix is added by the kernel. For messages sent by user-space to the kernel, you must adjust the prefixes according to these flags
