Currently if generic_buffer is invoked without first enabling any channels in scan_elements/*_en, it will fail unable to enable the buffer because bytes_per_datum inside the kernel will be zero if no channels are available. It is implied that the user of the program should enable channels manually or with a script before executing generic_buffer. Be more helpful by stopping execution if no enabled channels can be found, and print a helptext that will tell you what is wrong and what needs to be done.
