you're right under /usr/keys/...
i have 4 files only for the emulation sofcam.key link for file
usr/keys/...
- ncam.conf (only with info emu)
- ncam.server (only with info emu)
- ncam.user (only with info emu)
- SofCam.key
etc/tuxbox/config/...
- ncam.conf
- ncam.server (with your personal reader)
- ncam.srvid
- ncam.ccache
- ncam.fakecws
If you install "enigma2-plugin-softcams-ncam-2.6_openatv_armv7ahf-vfp-neon.ipk"
you have all file installed correctly
you just put your server on ncam.serveur in tuxbox/config/...
