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.
