To get a working usb network on "production" OS, copy devnp-asix.so from reformat package to /fs/mp/lib/dll/devnp-asix.so

1. pidin ar | grep usblauncher_otg
2. usblauncher_otg -S1 -c /fs/mp/etc/usblauncher/rules_otg.lua -M /fs/mp/etc/mcd.mnt -s /fs/mp/lib/dll/pubs/ -n/dev/otg/io-usb-otg -vvvv -b -eErtl
