Missing LED-HIDs (apart from ring HID)

Regular Visitor

I'm developing a USB HID device that interfaces with Teams.

I get ring-HID for Incoming Teams call, but when I accept I don't get the hook-off HID, nor any other HID from the same usage-page, like mute or hold.

Gotten the basic logs from the Teams app, but they don't reveal much.

Has anyone encountered something similar or might know the reason for this?

 

The device's HID report descriptor usage page looks like this: 

 

    Usage Page (LEDs)05 08 
    Logical Minimum (0)15 00 
    Logical Maximum (1)25 01 
    Usage (Off-Hook)09 17 
    Usage (Mute)09 09 
    Usage (Ring)09 18 
    Usage (Hold)09 20 
    Usage (Microphone)09 21 
    Report Size (1)75 01 
    Report Count (5)95 05 
    Output (Data,Var,Abs,NWrp,Lin,NPrf,NNul,NVol,Bit)91 22
