I recently got a Cougar 700m gaming mouse which does not work in Fedora 22. Running xinput lists it as a slave keyboard.

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

    ↳ COUGAR 700M COUGAR 700M Gaming Mouse      id=13   [slave  keyboard (3)]

Is there a way, short of recompiling my kernel to fix this issue?

uname -r : 4.0.4-303.fc22.x86_64

    This isn't a kernel issue: your mouse is advertising itself as a keyboard. Presumably it comes with a Windows driver that translates motion and the main buttons into mouse events and the keeps the rest as keyboard events. You'd need an X.org driver that does the same thing.

The previous answer, amazingly enough, works!

I have a Cougar 700m, and it didn't work in Ubuntu. Steps to download, patch and compile the kernel for me, on Ubuntu 14.04 LTS (mostly taken from https://help.ubuntu.com/community/Kernel/Compile):

sudo apt-get install linux-source
cd src/
tar xjvf /usr/src/linux-source-3.13.0.tar.bz2 
cd linux-source-3.13.0/
cp -vi /boot/config-`uname -r` .config
make oldconfig
make localmodconfig
make xconfig
cd include/linux/
(modify HID_MAX_USAGES as required)
cd ../../
make -j4 deb-pkg
cd ../
sudo dpkg -i linux-headers-3.13.11-ckt30_3.13.11-ckt30-1_amd64.deb 
sudo dpkg -i linux-image-3.13.11-ckt30_3.13.11-ckt30-1_amd64.deb 

It's a shame that you need a kernel patch for this sort of thing, but it was actually pretty painless to do. Of course, now I have to re-apply the patch every time I update the kernel...


Rebuild your kernel with the following patch:
