think the environment variables should be loaded before the device is registered,
so when the device is registered, it can be initialized according to the environment variable.

Please take look at drivers/usb/gadget/f_fastboot.c. it is already using
env variables.

When devices are influenced by environment variables they must be
prepared that these variables are changed *after* registration. Note
that environment variables are loaded from storage media that are
devices themselves, so that's a catch 22.
