hi buttersoft , Windows............when i have the Brooks plugged in via USB and power on the PC they come up in devices as unknown. But if i unplug then plug back in no problemo recognized , thing is i forget to do this before launching groovymame and all my controls disappear. Like i mentioned before your post i have set 'default.cfg' file to read only , this will probably prevent groovymame disappearing controls...... i'll know next power down and boot.
