Below is the complete .json file for checking computer_36_36276 (7).json

Hi @erique-souza
the relevant file for USB devices inventory on windows is this one: https://github.com/glpi-project/glpi-agent/blob/develop/lib/GLPI/Agent/Task/Inventory/Win32/USB.pm
Actually, it only uses WMI to retrieve connected devices and nothing more is done to find more information like serialnumber if it is not found. You can see what's the agent analyses by running:
wmic path CIM_LogicalDevice get /format:list
From this list, only devices for which DeviceID
field matches /^USB\\VID_(\w+)&PID_(\w+)\\(.*)/
regular expression will be recognized as USB devices. And we only try to extract S/N from this ProductID
field.
Can you still share at least the entry related to your device ?
To support extracting S/N from registry for some case, dedicated modules will have to be created. My guess is we can use "productid": "C902"
& "vendorid": "1753"
to trigger the module, maybe just on vendorid
like the way this is done for monitor in Screen.pm to trigger modules from lib/GLPI/Agent/Tools/Screen
folder. Using this principle could permit users to develop their own module.
Can you share an export of HKEY_CURRENT_USER\Software\Gertec\PIN Pad
to eventually use it in tests ?

Understood, I can no longer access the equipment to export the exact record, but I made a replica on my Windows and exported it if I was going to use the data for testing
Gertec test.reg.txt I renamed the .reg to .txt, just remove the .txt to access the file correctly
Okay, the wmic output would have been useful for automatic tests, but I still can guess it from the json output.
I think I can try to develop this support anyway as this could be an interesting update.
Hi @erique-souza
I see a problem in your registry export: it's under HKEY_CURRENT_USER hive... do you have the same keys under HKEY_LOCAL_MACHINE ? This is a problem as the service is running as LocalSystem user.
Hi @g-bougard
without feedback, I'm closing this issue. Feel free to reopen or comment.

Describe the bug
I'm trying to inventory the USB device Card Reader model PPC 930 from Gertec, in Windows there is the full driver for the device, but the GLPI-Agent when importing only brings this data in the .json file
The device's serial number is missing, but this information exists in the Windows registry in this path: Computer\HKEY_CURRENT_USER\Software\Gertec\PIN Pad as shown in the print below
I would really like to know how GLPI-Agent exactly collects information from device drivers to always try to check the correct path of how the reading should work
To reproduce
Expected behavior
The device inventory along with the computer inventory in the Devices tab linked to the asset
Operating system
Windows
GLPI Agent version
1.7.3
GLPI version
10.0.14
GLPIInventory plugin or other plugin version
GLPI Inventory v1.3.5
