My problem is almost same as in here & bug 1391260
Genius MousePen i608X doesn't work in Ubuntu
My OS is Ubuntu 14.10. The pointer moves, but no button is sensing.
It seems to share the same magic HID of the other
tablets of this vendor
Can I have a step by step procedure of downloading and installing the patch file?
Edit: After I upgraded the linux kernel version to 3.18.3-031803-generic, Genius MousePen i608X is working well.
