I get this error:

jmtpfs ~/mtp

Please report this VID/PID and the device model to the libmtp development team

can you also try mtp-detect as root to see if it works?

I passed to Mint 19. Now device mounts and is operational, but still this error:

i added the id.

Error6 means device busy, so it is likely used by another program like gvfs
