I tried, and they appear in /dev/myffs1 mountpoint alongside with ep0, and they

Hello.
I am trying to use configfs I/F of compsite gadget to add my additional EPs.
The EPs (multiple) are simple IN and OUT pipes which I intend to write/read on
peripheral (gadget) side user-mode application. I intend to use file
read/write.
As I look into the memos and driver source code,
eck mainline status
when I need to support (or try) other boards as well.

Now I am waiting for my USB-C breakout board to just re-using it for connecting
to conventional micr-A/B receptacle.
