I checked again. That looks like the file.
On this model, the usbdrive1 port is the android auto or apple auto port for devices, the second is just for storage or, an ipod.
Also, I'm getting this odd shutdown warning despite the lines in the sys.txt:
[power]
battery_warning_limit=0
powermgm_state=0
treat_charging_as_ac_line=1
