USB sound device block USB keyboard

Hello,

i have got USB sound card (Asus Xonar), but when is used, it starts blocking keyboard, after adding USB device dmesg recognise it as:

[   46.175715] usb 1-1.3: new full-speed USB device number 5 using xhci_hcd

[   46.502249] usbcore: registered new interface driver snd-usb-audio

I can't finde many topics about this problem, but some old suggest to change xorg.conf so I did like this

Section "InputClass"
        Identifier "USB SOUND CARD"
        MatchUSBID "0b05:17a0"
        Option "Ignore" "on"
EndSection

After restart gnome in Xorg mode it looks had some effect

But it does not work, just like in wayland USB sound card steal/block keyboard after system play some sound (eg bell in terminal) and few seconds after keyboard works again.

This problem is not isolated on this device alone, also got USB headphones Platronics HD1 500, they also block keyboard at least hedaphones have some keys, sound card does not :-D)

Not sure how to continune from this point any suggestion?
