Thank you for responding!

So i did those steps but the desktop environment didn't respond and nothing
happened (example: mute/unmute mic).

evtest showed the events though

Related to the camera, you are right the output is always the same when
pressing the hotkey:

vent: time 1671624629.967592, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671624629.967592, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 1
Event: time 1671624629.967592, -------------- SYN_REPORT ------------
Event: time 1671624630.042611, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671624630.042611, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 0

Using the switch on the side of the keyboard gives me this:

Event: time 1671624717.066109, type 4 (EV_MSC), code 4 (MSC_SCAN), value d9
Event: time 1671624717.066109, -------------- SYN_REPORT ------------
Event: time 1671624717.068528, type 4 (EV_MSC), code 4 (MSC_SCAN), value d9
Event: time 1671624717.068528, -------------- SYN_REPORT ------------
Event: time 1671624718.487656, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671624718.487656, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 1
Event: time 1671624718.487656, -------------- SYN_REPORT ------------
Event: time 1671624718.490199, type 4 (EV_MSC), code 4 (MSC_SCAN), value ee
Event: time 1671624718.490199, type 1 (EV_KEY), code 212 (KEY_CAMERA), value 0

Off: d9, On: value 1 and 0
