Hi, we still use g_ether but there seems to be a replacement:

https://www.collabora.com/news-and-blog/blog/2019/02/18/modern-usb-gadget-on...

Any ideas if and when we should try to set it up as default?

well, first what do we want to achieve and make available as wall-trodden trails to the user? I normally do not use g_ether and my gta04 is a combinated network-adapter, serial console, debian install cd and ordinary small usb stick.

g_ether is the default for accessing LetuxOS through USB. It allows to ssh into the device or scp or rsync files to it without opening it or setting up a wireless connection.

One more idea would be to allow it to be mounted as an USB memory device so that the /home directory or some files can easily be accessed. Similar to how the tolino ebook reader is showing itself.

well, the partition is afaik umounted for that. At least the kobo then does not allow other usage.

So my idea would be to provide a tested and working standard-install to modernize g_ether by the configfs and add something like g_storage.

What I don't know is if it is possible to have both in parallel... I.e. that a device is mounted as a memory device and we can still ssh into it...

having both as usb functions is no problem. My functions mentioned above work all together. But having both mounted read-write will probably create big chaos. I have a separate image for such things. That can even be a file to be loopback mounted. So I have some data exchange. Or a decision via some init script to mount the whole card at boot and do nothing else (sd boot). If we boot from nand, we could even export it during a normal boot.
