Hi,

thanks for the issue. I will check it and come back to you!

I think some kernels in the wild are built without CONFIG_IKCONFIG_PROC enabled, I'm not sure it's a good idea to rely on it. Edit: Or maybe missing gunzip binaries and needs to install busybox?

This is a bug which normally occurs when the app has no access to root. Fixed in https://github.com/tejado/android-usb-gadget/commit/7114806a163253bb6e0b7d9b06b627f9d5a07789 (not yet released).
