My keyboard’s (Nuphy AIR75 HE) function layers get recognized as a new USB device. This is probably correct behavior but I always get the KDE notification about a new device which is annoying.

I have created the following udev rules in /etc/udev/rules.d/70-nuphy75he.rules

```auto
 SUBSYSTEM==“hidraw”, KERNEL==“hidraw*”, 
KERNELS==“5-1”, SUBSYSTEMS==“usb”, 
ATTRS{idVendor}==“19f5”, ATTRS{idProduct}==“6120”, 
TAG+=“uaccess”

SUBSYSTEM==“hidraw”, KERNEL==“hidraw*”, 
KERNELS==“5-1”, SUBSYSTEMS==“usb”, 
ATTRS{idVendor}==“19f5”, ATTRS{idProduct}==“6f10”, 
TAG+=“uaccess”

```

The product IDs correspond to the ones when the keyboard is normally connected and when it is in firmware update mode. Journalctl reports product ID 6120 for each FN layer.

In normal use, I always get the new device notification when I activate a key from the function layers (increase/decrease volume, brightness etc). However, if I open the keyboard’s firmware settings at [https://drive.nuphy.io](https://drive.nuphy.io), then use an FN key, I won’t get the new device notification and the keyboard works seamlessly.

What am I doing wrong?
