Oh, I didn't saw that. I think it was owned by root because I did a modprobe gadgetfs first and later the same with the option (modprobe gadgetfs default_uid=1000). Now I have also my user as the owner, but qemu doesn't work with it.

I would test this but I don't know where to use this command. Where could I use this command?
