I am trying to get my Wacom Intuos CTH-490CK up and running under Arch Linux. The device is recognized and everything but the buttons work. However, most guides suggest to install the proper kernel module, which is not necessary when using a recent kernel (4.9.8-1 in my case). I read that removing libwacom and just installing xf86-input-wacom and input-wacom-dkms might fix my issues (post in german Arch Linux Forum), but trying to remove libwacom leaves me with the following error:

error: failed to prepare transaction (could not satisfy dependencies) :: libinput: removing libwacom breaks dependency 'libwacom'

Forcing the deletion of the package (pacman -Rdd libwacom) leaves me without mouse and keyboard or any external input devices. As I don't see a Wacom device in /dev I added a new udev rule:

$ cat /etc/udev/rules.d/10-wacom.rule 
ATTRS{idVendor}=="056a", ATTRS{idProduct}=="0084", SYMLINK+="input/tablet-intuos5-s"

This didn't work either. I also tried a manual setup using xorg:

$ cat /etc/X11/xorg.conf.d/01-wacom.conf 
Section "InputDevice"
    Driver        "wacom"
    Identifier    "stylus"
    Option        "Device"       "/dev/input/wacom"   # or the corresponding event?? for a static setup
    Option        "Type"         "stylus"
#    Option        "USB"          "on"                 # USB ONLY
#    Option        "Mode"         "Relative"           # other option: "Absolute"
    Option        "Vendor"       "WACOM"
#    Option        "tilt"         "on"  # add this if your tablet supports tilt
    Option        "Threshold"    "5"   # the official linuxwacom howto advises this line
EndSection
Section "InputDevice"
    Driver        "wacom"
    Identifier    "pad"
    Option        "Device"       "/dev/input/wacom"   # or the corresponding event?? for a static setup
    Option        "Type"         "pad"
#    Option        "USB"          "on"                  # USB ONLY

#    Option        "tilt"         "on"  # add this if your tablet supports tilt
    Option        "Threshold"    "5"   # the official linuxwacom howto advises this line
EndSection

    Driver        "wacom"

Do you have any suggestions on how to get the four hardware buttons on the tablet working and how I can bring up a device in /dev? Please find additional information below. If you need more just let me know,
