Cant make the kbfiltr example working

[massimilianoomero]

This is maybe more a question than an issue.
I'm probably doing something wrong but I can't make the kbfiltr example working.
Driver is not installing properly,
Here's the error:

This device cannot start. (Code 10)
Insufficient system resources exist to complete the API.

And his is the log in the driver events
Device ROOT\DEVGEN{14BD7B21-F5A0-5E40-8BE8-FE289A97CC87} had a problem starting.
Driver Name: oem156.inf
Class Guid: {4d36e96b-e325-11ce-bfc1-08002be10318}
Service: i8042prt
Lower Filters:
Upper Filters: kbfiltr
Problem: 0x0
Problem Status: 0xC00000E5

The only change I did (except some traces I added) was inserting the real hardware id of the device I want to filter.
The device is a footswitch with three pedals simulating a keyboard.
Here the logs in DbgView
--- FOOTSWITCH --- Keyboard Filter Driver Sample - Driver Framework Edition.

--- FOOTSWITCH --- NT_ASSERT 48 48 - This is OK !
--- FOOTSWITCH --- Exiting KbFilter_EvtIoInternalDeviceControl with status 0
--- FOOTSWITCH --- Exiting KbFilter_EvtIoInternalDeviceControl with status 0

Everything seems fine but the driver is not working. I can't understand why.
I'm not new to windows drivers but I barely worked with filter drivers.
I'm not using a coinstaller since I don't know how to use it and I read it's not strictly necessary in Windows 11.

Can someone please help ?
