First of all, fusioninventory and GLPI rock! Great job!

I have MacBook Pro (15-inch, 2018, 2,2GHz Intel Core i7, Intel UHD Graphics 630 1536 MB, macOS Mojave 10.14.6).

The laptop is connected to a Lenovo ThinkPad Hybrid USB-C with USB-A dock (type 40AF) via USB-C<->USB-C cable. Dock is connected to:

  • First monitor via HDMI->DVI cable
  • Second monitor via displayport->displayport cable
  • Logitech wireless mouse receiver

In order for the dock to be able to show stuff on monitors, drivers for MacOS have been installed from https://www.displaylink.com/

The problem is that the dock and devices attached to it are identified as storage devices:

Of course, the equipment is shown as storage devices in the GLPI as well.

Hi @AldarisPale
sorry for the delay, but can you report the output of the following commands, run as root or at least with admin rights:

/usr/sbin/system_profiler -xml SPUSBDataType
ioreg -c IOUSBDevice -r -l -w0 -d1

The first command will help us to filter out USB-C devices from <STORAGES/> list.
The second is to see if we see them as USB devices. If you don't see them in that ioreg command output, can you check the output of ioreg -l and tell us if they are seen as another class of device ?

I've run the commands you suggested.
iBridge devices are probably Touch Bar devices (https://lwn.net/Articles/786475/)
