Have you got thunar-volman installed?

Yes, if it is installed.

Is the system seeing it, can you mount it manually?

The system detect  on the terminal to Huawei,  but it does not display on the XFCE desktop, only the CD-ROM of huawei  is displayed on the desktop.
The CD-ROM can be manually mounted but nothing can be done because thunar does not detect the system of  the hardware of huawei. How to detect huawei in thunar and mount manually?

.........it already has libmtp onboard and that's been working so far.

............ but make sure the cable you're using to connect phone is charge-AND-data, not just a charging cable. This happened to me is why I mention it, it's always the little things in linux.....

Hello greenjeans!

Installed the  libmtp-common, libmtp-runtime, libmtp9, and there is nothing else with respect to libmtp, of the libmtp package those are all the first mentioned? The   package  mtp-tools and mtpfs are installed already,  and does not detect the device on the screen.

I don't know what happens with the systems of XFCE desktop , the devices are not automatically mounted on THUNAR, in this case Huawei is not displayed on the screen, in the terminal if it detects Huawei. 

With respect to the cable, this only happens on XFCE and thunar, other  desktops of Linux and Windows , if you mount it automatically and open the Huawei folder automatically.

I think you need mtp-tools and mtpfs

So far I haven't had to have those to connect Android phones to Devuan, it already has libmtp onboard and that's been working so far.

OP this may sound silly, but make sure the cable you're using to connect phone is charge-AND-data, not just a charging cable. This happened to me is why I mention it, it's always the little things in linux.....

Hello  fungus!

Corrected the topic, and  the  detection  the  terminal result. Can you explain how I proceed to upload the image here? Thank.

Huawei Smartphone  are not being mounted by Thunar but as you can see below, via the lsusb command, the system is seeing them. The system only detects in the screen the CDROM of Huawei  and detects nothing else, nothing else can be done, help?
