Hi all. I have Asus Xonar U7 usb soundcard, it has wheel for volume up/down and 2 mechanical buttons which are not important for me. Kernel recognized em as: dmesg | grep -i xonar [ 2.044929] usb 3-1.4.3: Product: Xonar U7 [ 2.055070] input: ASUS Xonar U7 as /devices/pci0000:00/0000:00:1c.5/0000:06:00.0/usb3/3-1/3-1.4/3-1.4.3/3 -1.4.3:1.4/0003:1043:857C.0006/input/input8 [ 2.105724] hid-generic 0003:1043:857C.0006: input,hidraw5: USB HID v1.00 Device [ASUS Xonar U7] on usb-0000:06:00.0-1.4.3/input4 Imho those imput devices should be catched by xorg and available to userspace(gnome in my case) for volume settings up, but totally ignored - tested with xev. Here`s xorg.log grep -i xonar /var/log/Xorg.0.log [ 2455.124] (II) config/udev: Adding input device ASUS Xonar U7 (/dev/input/event7) [ 2455.124] (**) ASUS Xonar U7: Applying InputClass "evdev keyboard catchall" [ 2455.124] (**) ASUS Xonar U7: Applying InputClass "libinput keyboard catchall" [ 2455.124] (**) ASUS Xonar U7: Applying InputClass "system-keyboard" [ 2455.125] (II) Using input driver 'libinput' for 'ASUS Xonar U7' [ 2455.125] (**) ASUS Xonar U7: always reports core events [ 2455.125] (II) input device 'ASUS Xonar U7', /dev/input/event7 is tagged by udev as: Keyboard [ 2455.125] (II) input device 'ASUS Xonar U7', /dev/input/event7 is a keyboard [ 2455.125] (II) XINPUT: Adding extended input device "ASUS Xonar U7" (type: KEYBOARD, id 14) [ 2455.125] (II) input device 'ASUS Xonar U7', /dev/input/event7 is tagged by udev as: Keyboard [ 2455.125] (II) input device 'ASUS Xonar U7', /dev/input/event7 is a keyboard So i wanna ask some help with it, wanna c it working :-) also its proven to work on laptop with other distro.
