Hi
As mentionned here (http://libmtp.sourceforge.net/) :
If you happen upon a device which libmtp claims it cannot autodetect, please:
Submit the vendor ID and device ID as a bug, patch or feature request on the Sourceforge bug tracker at our homepage.
Then, here is some informations. I hope they will be usefull.
The smartphone is a ACER LIQUID Z330 (http://www.acer.fr/ac/fr/FR/content/series/liquidz330)
As attached doc, please find the result of the command $sudo mtp-detect
Kind regards
