Thanks. Good to know it´s a know bug.
It happens with all usb controllers combinations, as soon as a mapped controller is turned off or unplugged when you launch mame/mess, settings goes to default.
Reports are from 4 years ago and still is not fixed
The workarounds works partially.
Hope mame dev team fix this.
Tested nes, snes, genesis, ps2, and a ton of other emulators, none has this behavior.
