This is the kernel module that is used to keep track of mtac cards installed on the system, and a set of functions for writing MTAC modules. This module has a dependency on the at24 driver's Multitech EEPROM patch, and the EEPROM data array it creates called "mts_ap_eeprom". To turn on debug add the following lines to the end of /etc/modprobe.d/mts-io.conf: options mts-io dyndbg=+p options mtac dyndbg=+p options mtac-xdot dyndbg=+p options mtac-lora dyndbg=+p
