/** @brief Read an Input report from a HID device.

	Input reports are returned

	contain the Report number if the device uses numbered reports.

	@ingroup API
	@param device A device handle returned from hid_open().
	@param data A buffer to put the read data into.
	@param length The number of bytes to read. For devices with
		multiple reports, make sure to read an extra byte for
		the report number.

	@returns
		This function returns the actual number of bytes read and
		-1 on error.
