Todd, https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/user_comps/mb2hal/m b2hal_HOWTO.ini This link says you can set a debug level.
#OPTIONAL: Debug level of init and INI file parsing. # 0 = silent. # 1 = error messages (default). # 2 = OK confirmation messages. # 3 = debugging messages. # 4 = maximum debugging messages (only in transactions). INIT_DEBUG=3 Maybe set yours to 3 to get more information?
